Telkom contracts

I've been a loyal customer for more than 15years. Since Telkom has been sold last year we've been having issues on my account. I've had a A53 5G on contract since 8 April 2022 which was suppose to end April 2024. My account has been billed with a R327.27 under Miscellaneous Carryover/Obligation which last debit was to be 5 June 2024. My new statement for July still shows the same amount to be debited on the 5th July 2024. We not told about the fine print about increasing of subscription fees either. Telkom just increases it but we signed a contract for 2 years. Before you had go in on the 23rd month to a Telkom to let them know you not renewing the contract. Now you must go in and on the day to end contract then you get charged a cancelation fee. So Telkom is just about money charged for them. Customers always get the short end of the stick and can gain. Even their accounts department is hopeless. So can someone help me with all honesty to sort out this account. They quick to debit but will not credit your account what is owing. So please people be carefull when signing a new contract with Telkom asking questions.
