Poor service

I had set a limit on a contract i had taken for my son in january, i noticed my account was debited every month with much more, when i went onto the telkom app i noticed that i was paying for the account that i had put a spend limit on. I had called customer service and was told that there was no spend limit set on that account, bur i had the contract infront of me stating that it had a limit of R1. The following day i called and spoke to consultant in the billing query department who also stated that she cannot see a spend limit on that account but was put the night before, i was told that a case was opened some1 will contact me in 24hrs. 2 days had passed no1 called to i called the store where i had taken the contract, the consultant assisting me said she can also see that this account never had a spend limit, but if i have the contract i must bring it to the store it could be a mistake due to the sales person not adding the spend limit. After i work i went to the store, only to attended by someone that was even more confused than me and cudnt give me and answer and was finally told that someone to call me back. Im still waiting for feedback, poor service, so many phone calls yet still no answers.
