Atrocious Service- Cell C

Hi there. I dont know if this is going to be worth me doing but I have tried every single avenue to try and sort this out. I upgraded my contract on the 14th of May, I was told it will be delivered within 3-5 working days. After 2 weeks of not receiving my phone or any communication I called and tried to cancell my upgrade because I did not want that phone anymore and there were other offers available and with phones in stock. I have made numerous calls ( i have lost count) and trips to stores in pmb who could not help me either. I have Spoken to 7different people who have said they have actually processed the request to reverse the upgrade and it will be done within 30 minutes every single time. And up until now it has not been done. I spoke to a lady yesterday who told me it will be done by last night at the latest and I can go in to store and sort it out today. I have stated numerous times in the last 2 weeks that I DO NOT want the phone if it comes back in to stock because there are better offers now for even better phones. Last night at 6.30pm the courier company arrives with the phone I DID NOT WANT! I did not accept or sign for the phone and asked for it to be returned to cell c. I cannot even express how frustrated and useless the service has been in the last month and am now at my wits end. I cannot explain how ridiculous and useless the level of service has been and for something as simple as this.
