MTN - Wrongful Cancelation of Contract

Mondo contacted me with a deal but the lady over the phone promised me a deal that didn't exist. I took it up with them and after a few months of following it up with them we sorted it out. They were going to give MTN instructions as to what had to be done. So I called MTN to hear if they had any news for me as MTN were still deducting money from my account with regards to the deal. The lady I spoke to decided to cancel the contract from her side. Not what I asked for! The long and short of it is, I had to pay up the rest of the money outstanding on the contract where MTN was concerned and Mondo actually gave instructions to MTN to pay out money to me because of the whole fiasco on Mondo's side. MTN can't help me. Must I start all over again, waiting for them listen to the call and phone them every 2nd or 3rd month to hear what's happening? The call center agents were not very helpful, one was plainly rude to me. I had to speak to someone at the ***** department to find out which department (retention) must help me and I actually spoke to the department (retention) more than once. MTN can't give me a reference number to follow this up and I'm at my wits end as to what to do! I must say, even though it took a few months to sort this out with Mondo they surprised me with the friendliness of their consultants, I can't say the same of MTN. Please MTN help me!!
