Unresolved query.

I never receive any feedback from MTN. Since i request contract that was app**** online to be cancelled, I am calling MTN and not getting assistance they say i must call Mondo since it was online. I call Mondo they told me to call MTN, I visit NMTN Boulders Mall Midrand and Mall of Africa they both tell me to call their head office and just give me number to cal. They dont even assist to call by them selves on my behalf at the branches all they do is to give their head office number, i dont know how much did i spend to visit MTN branches and to call their contact center without getting help. All i want is they exchange my package or completely cancel it if they dont want. I am stacked I dont know where I stand now they are just quite but my online contract was approved and they are expecting me to pay something that I dont have because the consultant say money will be debited. Is that how MTN treat new customers?
