harrasment

HARASSMENT ,this company continually sends me emails , sms's and phone calls regarding a autopage account, account number REF: ********** 53 that was settled and closed ON THE 18TH February 2016 , i have the paid up letter from Autopage , this was mailed to petros@vvm attorneys confirming this ,but it seems vvm attorneys have now sold this account to NORMAN bisset attorneys, I have previously stated to this company that they need to contact autopage to confirm this , but the response is autopage has closed down ,and they have no way of confirming this , so now they are trying to **********ly force me to pay for an account that had been settled, i have got to the point and told them send me a summons and i will respond with a lawyers letter as well as seek LEGAL ADVICE FROM MY LAWYER , they have gone as far as to email my girlfriend who died in August2017 , i have the proof of this as i have routed her emails to me
