Scam or genuine calls?

[eymorenos7]

Since last week I received some calls from different numbers saying that they are calling from the department of promotions of three and offering me a very interesting deal to change my iPhone if I take a plan of 24 months, I really think they are scammers but I want to be sure, these are the numbers:

01146979115

01313814383

01313814383

01615241425

01306866212

02081299424

01615249424

The first one based on my app for recognition of calls is Spam.

Hi @eymorenos7,

Those numbers are all impersonators. The fact that they constantly change the number they're dialing from is another indicator that this is a scam. Good spot! The link @Officina-red shared has some more advice, particularly reporting the offending numbers to the 7726 number will help our security teams in combating this.

Thanks,
Jonathan
