BAD SERVICE!!!!

I have tried since the 20th of April to get the "You are in breach of your contract" issue resolved on with M&Y!!! I have phoned numerous times (I have call logs and each person I spoke with) Sent numerous emails to *** and to date no one can exactly tell my why I'm in breach with my contract term. I was informed that there is a new term which was added that I now have to use more than 50MB of data, but I was never informed about this. I have requested proof for phoning more than 150 unique MSISDN numbers as well as proof that M&Y informed me about the change in terms and conditions. I have also on every occasion tried to speak with the manager/supervisor but he/she is never in or available to talk with me. On the 30th of April I tried to load 100MB data bundle on my account to try and avoid being migrated to another package, but the allocating a data bundle "had a technical error" as of the 1st of may I was migrated and no one still knows why exactly why im in breach!!! Lisiwe one of you staff also said to me that even if I did that I would still have been migrated as the THINKS im in breach due to 1550 calls rather not using enough data, SERIOUSLY!! How can you migrate me but your staff cannot tell my what im in breach for. I have sent close to 4 hours on the phone to get this resolved with many promises that your team will phone me back, to date I have not received 1 phone cal to try and get this resolved. PLEASE PHONE ME
