Cell C is a Disgrace

I was on a top up 100 contract package which i upgraded from in May 2018. I was upgraded to a sim only package (10GB day and night data only). I received a text today stating that I have received 22mb data, 22 sms's & 22 minutes. I called in numerous times today asking why this has been changed as I did not request anything. No one could assist as they do not know why this happened. The last lady I spoke to advised my contract was reversed by someone working in their customer service dept but was unable to give details as to why it was reversed, stating that no notes were left on my account. I DID NOT AS FOR THESE CHANGES TO HAPPEN ON MY ACCOUNT. I did not give CELL C the authority to make changes on my account so now I am left with 22mg of data on my phone instead of over 2GB i still had this morning. And all they can say is they cannot assist and they don't know why this happen and they cant reverse their mistake, only put me on a new contract today which is NOT what I want. Cell C you are PATHETIC and it's NOT the first time that I have been **** to about my contract.
