According to my records I settled an account which now reflects on my record.

I had a cellphone contract with Telkom and after the 24months I did not go for an upgrade, I was then given a settlement amount by the call centre which I paid in cash at an Absa Branch, I have no longer got the receipt. More than 2 years go by, not a word from telkom and now when I am wanting to do an application, Telkom appears to be on my record. I have made numerous calls to Telkom to dispute the ‘outstanding’ amount that now reflect on my name. I have not got a device or sim relating to this account. According to the call centre this account does not reflect on my ID number but when I quote the account number it appears to be an arrears account on my name.

Please advise how I can be billed for a cellphone contract if I have not upgraded? An how can this now be a bad reflection against my name years later
