Africa Mobile bridging Contract agreement

I am Mr Mlotha and i have a Cellphone contract with Africa Mobile company. According to the contract we have is that, they will give me a Cellphone with data and airtime for a period of 36 months and i will pay them R664 every month.

Than i choose a Cellphone device Huawei 11i nova.

But the problem started in when they don't give me airtime and Data. And i contacted them to notify them that i never received my Airtime and data as per agreement. That was on the 2/07/2024.

I keep pushing and they also promised you device will be recharged up until today on the 23/07/2024 where i saw a debit order from them taking another money while they have not recharged my airtime and Data.

And i called them, because if it was myself who did not pay them my Cellphone was going to be blocked. But in this case they can still not recharge my device as per contract and still continue to debit me. Worse part on our agreement they have to debit me on 25th of every month but this time they took on midnight 22/07/2024.

So this company is not loyal and doesn't keep their promises to their clients and not respect the contract we have with them. They go as far as abusing my bank account as they do as they like out of our agreement.

They lady i spoke to this morning told me they have experience problems but on my surprise no one had communicated that with me. I only got to know about that after i saw a debit order. My question now is it wrong of me if i sue them on bridging the contract that we have?
