Absolutely Useless

I activated sms roaming when I left SA on the 14th January. I returned on Saturday 21st January and I have been struggling since Sunday morning 9:00 to deactivate this service. I get told to use the *135# service but that tells me to call the callcenter but WOW. I have been pushed from pillar to post and all I get told is they are escalating it and the system is the problem. The callcenter is probably the most useless one around, I have been cut off more times than I care to count and dont seem to be going anywhere. Every time I get a new reference number and we start all over again. I would rather deal with Eskom than the MTN callcenter. If I could rate less than 1 star I would as they dont deserve 1 star. I then ask for retentions to cancel my contract, thats an even worse of a joke!!!!!!!!!!!!
