POOR SERVIC FROM MTN

I loaded R50 airtime on Saturday the 1st and did not make any calls,as the number i tried calling no one picked.Then i woke this morning to R0 airtime so I called MTN and Siyabonga answered saying I subscribed to Base play games,and i asked when was that cause this has never happened all he could say was "I am sorry" with no explanation.Not how much it cost as I was aware of the ringtone that I also did not subscribe to but must have gotten it from my husband as he has a ring tone when i call him,and MTN does that,bit because its R1 a week I did not care,Siyabonga had no answers to my question like when did I subscribe as this has not happened to me before,again he just said "I am sorry and please do not load any airtime today,I got upset and dropped the call,then I called back and spoke to Nomasuku who also did not listen to the reason for my call instead she just said she cant say how much this base play games cost,because I unsubscribed and It wont show the price, which I find very concerning,you deduct my money and you cant tell me how much the service cost,I asked for an email address for a manager and she just kept saying she wont be able to tell me the amount as I unsubscribed and she does not have the amount.I work at an Ombudsman and I know how customer service should work,Its the worst service I received and worst they not properly trained to provide feedback. I deal with upset consumers which we assist at no cost but I still have the answers and receive weekly training in order to assist consumers accordingly.WORST SERVICE AND WORST NETWORK...
