Uncapped wifi or uncapped worries?

I have home wifi from MTN which is the highest mistake I have ever made. According to the outstanding amount from the ***** department at MTN which I had to contact because nobody from MTN customer services ever calls regarding any issues, the outstanding amount is rounf R140. Today only R742 has been unsuccessfully debited from my bank account which causes incurred bank costs (this was done numerous times last week aswell. I can pay the account per banking app as my mother-in-law went through just under 16k *****ulent activity from MTN that had to be resolved. The only reason I decided on MTN was the special for uncapped wifi but apparently they also give uncapped **** for their customers to worry about. They also have absolutely no account information for accounts as the amounts are always wrong. I would appreciate feedback and fix on this as I am honestly fed up with the ********** service from MTN this far.
