Request to remove comment of phone number

This number has called me on numerous occasions on both my works mobile and my home number. I rang the number back and got to what they said was their "Customer Service desk" they then proceeded to say that I had made an overpayment on my account they said they were from "Royal Assurance" I hung up immediately because this is a con. I do not have any insurances with this company. Please be aware that this is a con even if you ring them back the scam sounds like a busy call centre please be AWARE and do not give any personal information.
