Contract Terminated and reinstated with a new start date

Telkom has terrible customer service , i took out a contract with Telkom in 2021 March and the contract is suppose to come to an end ,March 2023 , someone internally terminated my contract and restaterd a new contract with a new number and new contract date , meaning my contract is only ending 2024 for a 24 month contract that was raken in 2021. I have been to 4 telkom branches i have been told i must call the contact centre ,since they cannot assist , i been taken from pillar to post ,doing affidavits no one is really assisting with this query , i then tried again today went into the rivonia Branch but no seems to be able to resolve this issue , its frustrating and time consuming ,i have sent emails to numerous people at Telkom still no one can take accountability and resolve the issue .
