Poor service

Hi, my account have been suspended by Telekom since Saturday 21/12/2019. I called telekom asking why did they suspend the account sine am not owing anything the next debit date is 25th Dec 2019 and I paid on Nov, I was told that it was suspended by collections department they don't know why because they can see in the system that I don't owe anything. They've been escalating the issue daily since Saturday telling me to wait about 5 to 24 hours till today 26 Dec 2019 am still waiting and I keep on calling them daily but there is nothing done. They just tell me they can see it has been escalated by their manager to wait 5 to 24 hours everyday. They normally debit my account on the 25th and they did on the 24th since 25th is holiday but my number is still suspended. When it comes to debiting my account they don't have any issues but they just suspend my number with no reason and they doing nothing about it. It's about 5 days now with the suspended number with the free minutes and data. I just want my account unsespended or open because I upgraded on the 29th November. If it was possible I would actually like to cancel the contract this is too much.
