01289222041 – North East of England
Overview:
The number 01289222041 is frequently reported in the North East of England. This number is associated with unsolicited telemarketing calls, typically promoting various consumer services. These may include offers for new energy plans, insurance, or even holiday packages. What makes this number notorious is its use in deceptive marketing practices that fail to fully disclose the terms or costs associated with the services offered.
Why It’s a Problem:
Consumers have raised concerns that the calls often begin with a generic pitch, followed by hard-sell tactics that can feel pressurizing. The most notable issue reported is that many individuals are unable to unsubscribe from these calls after engaging with the number. In some cases, the callers claim to be affiliated with well-known companies, making it difficult to discern whether the call is legitimate or a scam.
01952446550 – Telford
Overview:
This phone number 01952446550 has been flagged primarily for involvement in fraudulent investment opportunities. Often, these calls offer “exclusive” investment opportunities in commodities, real estate, or cryptocurrency. According to complaints, these calls often come from aggressive salespeople who attempt to convince people to invest large sums of money.
Why It’s a Problem:
The biggest issue here is that these types of calls are often associated with investment scams. Victims report that after providing financial details or making an initial investment, they are unable to access their funds, and the scammer disappears. As with many investment scams, the promise of high returns within a short period often proves to be false.
01205386545 – Boston
Overview:
The number 01205386545 hails from the Boston area, and it is predominantly associated with PPI (Payment Protection Insurance) claims. Since the PPI scandal, many companies and individuals have been bombarded with calls from companies promising to help recover mis-sold PPI.
Why It’s a Problem:
While some of these calls might be from legitimate firms, there have been numerous reports about companies claiming large fees upfront before any work is done. A large portion of the complaints involve these calls being misleading about their success rates and charging excessive fees for services that were available for free through government-backed services.
01389493417 – Clydebank
Overview:
The phone number 01389493417 is associated with calls offering personal loans. These calls often claim to offer quick loans without credit checks, which is highly enticing to individuals in financial distress. However, the loans typically come with hidden fees or extremely high-interest rates that trap individuals into cycles of debt.
Why It’s a Problem:
This number is frequently reported for loan fraud. Scammers often prey on vulnerable individuals who are looking for financial relief. The calls frequently involve promises of “easy approval” and “no credit check,” which is often a red flag. Those who fall for these schemes often find themselves with exorbitant fees and interest charges, and many times they are left with no way to contact the lender again once they realize they’ve been scammed.
07418374545 – Mobile Number
Overview:
The number 07418374545 is one of many mobile numbers used for fraudulent surveys. These calls often claim to conduct research or surveys and promise prizes or vouchers to those who participate. However, these surveys are typically a ploy to get individuals to provide personal details, such as bank account information or social security numbers.
Why It’s a Problem:
The primary concern with calls from 07418374545 is that they are part of a fake survey scam. The scammers often claim that people have won a large prize and need to confirm their identity by answering a few questions. These questions are usually designed to gather sensitive personal information, which can then be used for identity theft or fraud.
