Ridiculous standards and poor service

I was due for an upgrade on 22/10/2015. I went across to Tygervalley to arrange the upgrade, and hopefully get the phone straight away, I did this even though I knew it would cost R100 to do the upgrade in person. They were out of stock of the phone I wanted. They then tried to sell me a model I didn't want, after which they asked if I was willing to wait for one to be sent through for me, which would take 2 days. I said I would wait, and filled out all the documentation. 2 weeks passed without any communication then suddenly they phone me and say the phone is back in stock, would I still like to have one. I said great and told them I could only come in the next day. Today they phone and tell me I need to come in right away because they cannot keep the phone on hold for more than 24 hours. ***! It is not even 10AM, not even a day has gone by since I confirmed that I would take the phone, and I must jump up from my job and go and get a phone immediately because they can't wait more than a day to give me a phone that I have waited more than 2 weeks for, without a single word of communication about the progress in that time. Cell C, what ********.
