Poor Service, Time Wasting and Lies

I phoned your upgrade department on Wednesday because I wanted to pre-order your current S10 special with the buds, voucher and extra 50gigs. The man on the phone told me I could upgrade now and would receive the phone in 3-5 working days. I went through the full process with him. He told me I would recieve the phone etc. now and my current contract would run to July afterwhich the new upgrade contract would kick in so I wasnt double paying. All fine. Yesterday I checked my online account and realised nothing had been processed so I phoned Cell C. The lady on the phone said Management had stopped all pre orders on specials till today as you had a stock take issue and to call back today. This morning the man I originally spoke to told me I could not recieve the buds unless I go into the store, I asked him if my upgrade was processed, he said yes, I just needed to go into any store to process the final upgrade and collect my goods. I took time off work to do so as I have been using a broken phone ever since August 2017 when I was assaulted and ******. So you can imagine how much I was looking forward to my new phone. When I went into the store, your workers were very reluctant to help me and told me nothing had been processed and in fact I cannot upgrade until 21 April!!!!! Not only has my time, money and patience been wasted but I am paying a service provider who treats their clients like garbage! I am beyond upset and would like to know what Cell C are going to do to keep me and my family as customers?
