arrangements

once again MTN has not failed to disappoint me the sad thing is I really enjoy being on this network but the way I am treated whenever I need help is appalling. My contract ended in September 2014 however I was in in arrears and I was behind by 3 months. I made arrangements to pay my account over 3 months and also requested that the contract be cancelled as I was no longer in need for it. the consultant I spoke said they would call me regarding the cancellation to this day I am still waiting to be called back. My line has now been suspended and even after I made arrangements MTN continued to supply me with my monthly top up package of which I requested be cancelled. they then billed me for that and increased the amount that I owed them from R1200 to R1600 to now R1900!. the consultant I spoke to said that they can't stop the package until my acc is up to date. how will that happen if every time I make an arrangement the money increases. I will never finish paying if that is the case. I was then advised to call the legal department as they might be able to assist with getting my line active again and that didn't work even after sending them an email I still haven't been called!!
