*****ing Airtime! No Assistance

I'm on a contract where I get 10000 free MTN to MTN minutes and 100 anytime minutes. For the last month MTN has used up all my anytime minutes when I call an MTN number and not the MTN to MTN minutes. We've reported this to the call centre and have had no assistance. I've now been purchasing airtime almost daily, and MTN has used up my airtime instead of the MTN to MTN minutes. Today I have 200 mb of data left on my phone, and when going on the internet it has taken R60 of the airtime I've purchased and not used the data. I've tried to get assistance from the call centre but every single time I get through they answer and cut the call. I eventually got through and spoke to Thembisile who firstly was so rude when answering the call and refused to help me saying the contract isn't on my name, even though my husband has on numerous occasions made me a beneficiary on the account. Not even the supervisors or managers wanted to assist. I am so sick of MTN and now you are *****ing my money and no one wants to help. This has been going on for weeks now. STOP *****ING MY MONEY! This is completely unacceptable! I WOULD ADVISE EVERYONE NEVER TO USE MTN AS THEIR SERVICE PROVIDER!
