MTN Contract - Shocking Customer Care Service

I took out a 200GB monthly contract with MTN in July 2023. It started off okay and then it has just been a shocking experience. On the 10th of August, I was told I had run out of data - which is absolutely impossible!!! We only watch 1 episode of series each evening on the lowest quality. In the meantime - I put in a back up pay as you go SIM card, with this SIM card we have not used more than 9GB in an entire month. The contract SIM card then sat on the shelf (OUT OF ANY DEVICE) from 10th August until the 12th September. It was at this stage I started emailing customer care and to date I still have not had any responses in resolving the issues I am experiencing. To try and phone customer care is an absolute waste of time as you cannot speak to a consultant for assistance - I have tried this many times. Eventually I got a response on 12th September to say we have 321GB of data. We put the SIM card back into our device and used it for 3 episodes on lowest quality - after 3 days came the message to say we had run out of data. How is that even possible?? On the 17th September - I received my itemized billing statement, on this statement it is reflecting data usage on every day between 10th August and 12th September - baring in mind that the SIM card was NOT even in a device during this time period but rather sitting on a shelf!!!!!!! It is totally outrageous!!!! I am paying monthly for this contract and they cannot deliver the service promised - but instead seems they are actually *****ing from me and reflecting data usage on the SIM card when it hasn’t been in a device!!! I am at my wits end with this and I cannot get anyone at MTN to sort this issue out which is why I have turned to Hello Peter as a last resort! If there is anyone that can help me with this issue, I would be most grateful.
