Quick to deduct, but slow in service

Mtn called my father for an upgrade several times, after he told them that he would rather go in to an mtn shop to do an upgrade they still phoned him. We went to an mtn shop in Queenstown, Nonesi mall to physically do it, because of my fathers illness i accompanied him. On the day the phone arrived that we ordered from the shop, where we just had to go pick up the phone. one of the Sub contractors of Mtn, mondo mobile, phoned my father again to do an upgrade, as he thought it was mtn, as they told him, he said yes. so i had to go to the mtn shop to go and ask them to cancel that, they told me they cant as they already did the upgrade and send my father a message stating that the upgrade has been done. all of that happened on the 5th of september. It is now the 12 of October and no phone arrived, but they already deducted the whole amount for a phone that my father never even recieved. I tried phoning, as well as my father. they cant answer our questions on anything we asked. we phoned and email mtn and all they can say is,phone this number ********** 583 'mondo mobile'. Mtn and Mondo mobile is playing a blaming game. Its a month since this upgrade was done and my father still have not yet received anything. not even a Reply. I am really disappointed in this, as my father is a loyal customer to mtn all these years. If i could give him advise it will be that he should just cancel everything with Mtn. Even reading through the Consumer Acts, i wish to send this situation to every family member warning them about whats happening to my father and stop them from entering into something similar. i hope my father will get his answers, or his money back or even just to get his phone, so after he is done paying the phone he should just cancel his contract.
