ENOUGH IS ENOUGH 6 YEARS LATER AND YOU WANT ME TO PAY WHAT????

If I could do a -star I would. Around 6 years ago I had my contract, that had expired and was on month to month basis, put onto pay as you use. I was advised that this would be done at the end of that month. After few years later I was contacted by lawyers icw Cell C account that I am owning. I advised them that I was on pay as you use and the contract everything was closed years before. The caller then asked if I could go to a shop of Cell C to get confirmation that I owe nothing to them and account closed which I did at the N1 City shop. They advised me that they can't give me anything but assured it was all closed and said "why else would they put your sim on pay as you use" but I should call the call centre. When I phoned the call centre they confirmed that account closed and nothing owing. I requested a Ref no which I phoned the attorneys and gave it to them saying they would come back to me if necessary. NOW I get calls and sms's from lawyers after now 6 years since cancelled with Cell C from attorneys SSDA that I have outstanding amount owing to Cell C. I have received a sms on the 25/8/22 with bal owing R437.31, sms dd 29/8/22 payment on cell c acc is overdue urgently pay R250, 30/8/22 they want proof of something, who knows what??? The previous sms's I have deleted from attorneys SSDA. Today I get called and said that I have an account outstand of over R500 *** ?????????? NEVER HAS CELL C CONTACTED ME!!!! Every time someone phones I tell them to read the previous callers details. I am on Boarded Medical Leave for Very High Anxiety and Stress Disorder and Depression, and they keep on phoning me. But never the same person. ENOUGH!!!Cell C has been the WORST cell phone company I have EVER dealt with. If they can't give me the details that the account is closed no money owning what must I do? Over 6 years they want WHAT??? They have NEVER given me proof or as I said contacted me. They are lucky I am not suing them for the stress and anxiety attacks I have been going through
