Mtn bad customer service

We took a wifi router on the 5th of December 2024 on a home premium 35mbps uncapped and we paid the pro rata and January premium. On the 17th of January there was a debit order which returned unpaid as that was not the agreed to debit order, a few days later the router was blocked, we went to Menlyn to enquire we we told that they don't understand why the device was blocked because it reflected that we still had money credited in our account and the device was reactivated. On the 29th of January the device was connecting but without internet access. We called the customer service line and we were told that the account is in arrears and on the payment is received then the error will be resolved. A debit order went through on the agreed date 04/02 we called and were told that the bearings needed to be reseted and told that we were told to switch off the router for 5 minutes and all will be reseted, that was on the 5th at 13:20, I have been switching the router on and off since still no internet access, when we call the customer service line we are being sent from pillar to post and no resolution has been found even today 06/02/2025 @18:00. Anyone to assist, every time I call I use minutes, I am a vodacom and Telkom cellphone user. Please help me
