I owe telkom R121 000 on the bureau..how is this possible

I was a director of a logistic company from 2016 and opened a Telkom account on 2018 when the company needed office components such as phones and laptops . We had bought these items under an account and were paying them . A year or two down the line we had missed a few payments and the account was under review. I had tried making arrangements with Telkom but seemed to get no where with their customer services . Then covid hit and no communication was made between me and Telkom to a point where I couldn’t even find my account anywhere on the Telkom app . It said my account has a zero balance. I then noticed that from now till then Telkom has a balance of 121 000 on my credit bureau. I tried calling Telkom to find out how much I had then paid and how much my actual balance is and they said they can’t find it on their system and seems like it’s paid up . Iv tried applying for other things and can’t because my name is still highlighted with Telkom but Telkom can’t seem to find my account or who they handed it over to . My credit profile is healthy but can’t get anything anymore because of this and it’s frustrating. I feel it’s unfair that they can’t trace my account but still I’m listed on the bureau because of them . There is no way I’m owing Telkom 121 000 . I need help and it’s very frustrating at this point . This is a 2018 issue till now . Iv logged disputes and I have been told it’s been solved but it hasn’t been solved . We had debit orders that can’t be traced now from them but I owe them so much money ? Help me I’m suffering . Their customer service doesn’t even help , never have answers
