****ed with telkoms customer service

Me and my husband went to Telekom in canal walk to apply for a hp laptop that was advertised I there catalogue. After waiting more than an hour we were eventually helped. We were helped by guy name Keenen or keagan. He ran the application and everything was approved and was given an order number. The guy said that he will receive the laptop as soon as stock has arrived. Bear in mind that we did the application in March and end of April we did not receive any feed back. On the 5th of May we made our way to the store again waited an hour or so to be help eventually we got help and was told there is no stock again but the very same laptop was still being advertised in May. We asked the guy if we could opt for a other laptop instead and was told it won't be a problem. The guy did the income and expense so that we could see if we qualify for the lenova i3 laptop. Once every thing was done he told us that it has been approved and that my husband can expect a call by Tuesday the 8th for collection. We waited for that call up until today the 16th of May. My husband then went into the store to go find out and he was told that he does not qualify for it. So how in heavens name is it possible that one minute you approved and then the next minute you not. I am really ****ed off because he was surpose to use it for his studies. I find it unexceptable and Also that they *********** in what they doing. What kind of customer service is that? Why didn't they have the decency to get back to there customers and inform them or send a sms/email regarding there devices.
