Disappointed

I received an sms from cell c about a contract that was just for today.. I went to the store at Westgate mall Mitchell's plain just to hear that they Out of stock and they could not do the up grade if they don't have the phones.. the last that assisted me said that she wi'll get back to me to tell me when the stock will arrive and she did there was no stock at all... I was disappointed cos now I cannot get, the contract at the price as it was just for today (very sad)
