Very poor service from Cell C

Good day, I am very saddened to have to write a poor review about a cellphone service provider that I previously thought was one of the best, on the 9th of September I app**** for an additional line on my existing contract for WI fi and a router, the sales man "Fana" was very decent and was doing his job well and I was happy to take the offer he gave me, but when it came to delivery he did not inform me that I needed a proof of residence before the courier guy would release my goods to me, so unfortunately the courier took it back, the next day the sales rep phoned me again to state the delivery was unsuccessful and that if I have my correct documents now that they will deliver within the course of the day, when 1pm came around I phoned to follow up with cell c as the delivery had not yet arrived and I spoke to a lady rep who's name I can't remember now, but she assured me that by 3pm I would receive the package, she also assured me 3 times after that that I would receive the package that day before close of business, this however did not materialize, I sat at my work place until just after 6pm waiting for this package that never arrived. the next morning September 11 I spoke to Fana again and he begged me to just give him chance to make sure the delivery was done that day and he too promised me it would be by 3pm that day latest that I would receive the package. This did not happen and I eventually phoned cell c just after 4pm to follow up and to speak to the supervisor by the name of Spiwe. He assured me that the package is definitely out on delivery and I would receive the package before I leave work. Then at 16:15 I received a call from the courier dispatcher who said he will deliver the package but he's not certain if it will be before 5pm, so at that point I decided to cancel the order and I told him not to bother to deliver and that he can just return the package to cell c. The next day I phoned cell c just after 8 to process the cancelation of my order and the supervisor Spiwe had acknowledged that he would process the cancelation. I am writing to hello Peter because I was given a very poor service, and did nothing to really save the sale or pacify me as the customer. This morning 26th of September 2019 I am still receiving sms messages stating that the delivery will take place today! Was this contract ever canceled?? Will I be billed!? I'm extremely unhappy and need this resolved
