MTN service provider

Good day I have taken a wifi package of R399 120GB 60 / 60,with MTN. Date mid November 2019,not sure of the correct date. 1. Firstly I have been debited incorrectly. Raised with MTN. Still no feedback. 2. For the last 4 days I am unable to connect. Remaining data. 105.39GB. Numerous emails sent to MTN customer Care. I keep getting replies that I have 105.39GB, no one seems to understand. I have reset the router numerous times, still no luck, still cannot connect. My sim card has been reset by mtn, still no luck. I am not getting alternate solutions.

Mobile number for wifi. ***
