CellC - Incorrectly handed over to attorneys

I terminated my data contract with Cellc in 2020 and made the termination payment at the store then, now two years later I am being harassed bt a company call Shapiro Shaik Attorneys requesting me to make this payment them I was wrongfully listed for or to send a paid up letter.

I then went to CellC store at The Glen Mall to request their letter or to get the relevant contact number to escalate my problem but unfortunately I was advised that I cn only br provided with an email address that I can use as a contact medium and I have since sent them a mail last week and have still not recieved a response, the most frustrating thing is that this listing is going to affect my credit record negatively and sete and family back. The second biggest issue is that these Attorneys call me 3/4 times in one day harassing me to make this payment.

I am still waiting for my paid up letter and to be cleared at the ITC
