Caller had very heavy accent, Possibly indian im not sure. Was definitely a scam, But I wasnt sure. I asked them to quote me my account number and they quoted the wrong number and I told them. He said ' F*&k off you motherf*&cker' and then hung up. So yes, Definitely a scam. Dont trust anyone.
This number called me pretending to be TalkTalk engineer and saying that my line is faulty. He even give me my account number, My IP address, He also given his address in London (don't exist)? And all the info he give me is wrong.
Is a fraud, Trying to get into others' system. Should be investigated by the police fraud department
