WHAT TO DO IF I HAVE CANCELLED A CONTRACT AFTER 2 DAYS

I wanted to take out a contract from MTN (as party of a gift for my daughter for Christmas). Huawai P8 lite. After reading all the back reviews about MTN, I decided to cancel the contract, I called their HO 011 912 300 several times, as it was humanly impossible to get help from any of the numbers that was provided to me, I was told not to worry, as long as the sim has not been activated, I would not be charged. The phone was delivered to my work but I sent it back, I never signed for it, as I did not want anything to do with MTN.

When I wanted to take out the contract, I told them that I want my daughter to keep her same number. They have now migrated my daughters number, after I have proof that everything was cancelled and now my daughter cannot use her phone, She has no signal whatsoever. On Saturday in the pouring rain I eventually got through to some operator who told us that I had to go to my nearest MTN store as I wanted the number to go back to Cell C but they could not help me on the phone. In the rain I went to our nearest MTN store (Lambton Mall) to be told that they cannot help us and that MTN's call centre is getting them into trouble as all the customers are screaming and shouting at them. Guess what - the no the guy gave me did not even exist. I have sent so many messages on facebook and facebook messenger, but nobody seems to get back to me. HOW ON EARTH DO I GET A RESPONSE FROM MTN TO SAY THE CONTRACT WAS CANCELLED AS I NEED TO TAKE OUT ANOTHER CONTRACT FROM CELL C now as her Christmas gift. I cannot believe that all the people I have spoken to in the past 3 weeks have been so unhelpful and does not give a damn about customer service

Surely there must be someone with some authority that can help me. I have given them my ID no via FB Messenger as well as my contact no, and guess what, nobody has been in touch, I have spent the ENTIRE DAY on the phone to MTN calling various numbers but to no avail. Louraine Msenya and Tiny Tsele was suppose to call me, I am still waiting. ********** I have sent 3 messages to this lady (Masipo) who has been the only one who has been trying to assist me, but also have not heard anything back from her.

I need to take out another contract and NEEDS TO CONFIRM THAT THE CONTRACT that I WANTED TO TAKE OUT WITH Cell C has been cancelled. We have been with MTN since cellphones came out, and have had a bad experience about 4 years ago and that made us switch over to Cell C. THIS IS WHY MTN is loosing customers and they are going to keep on loosing customers. PLEASE CAN SOMEONE HELP ME
