boo on you Mtn

Out of years of having my contract I all of a sudden get a R10 000 bill. NEVER IN MY LIFE. I usually get a message saying my account is capped, not this time.....CAUSE YOU ALL ON STRIKE!!!! So I reversed the payment and put a stop order on my account. I have lodged a query in May and no one has even bothered to look at it. I keep wanting to sort this out as a good payer of accounts, I will pay my subscription fee but not this other ****. I have called the call centre several times, phoned the head office, useless, and been to the store. Nothing can be done they tell me. Well guess what MTN, I am immigrating so the joke is on you buddy. I'm trying my best and all you can do is f/^??ING strike, ****** useless I tell you. SORT THIS S$%T OUT!!!!!! You probably going to end up going bang with all idiotness going on.
