Poor service

My wife and myself app**** for new cellphone contracts (huaweii p7) at the new 'state of the art' Telkom mobile a week after it opened. The deals available were advertised extensively in brochures and on huge television monitors in store. We told by the assistant that they did not have stock in the store but that we could fill out applications and would be advised when the stock arrived. Because my application was for a contract for my teenage daughter I had to provide a 3 month bank statement for which I had to pay almost r80-00 at my bank and go in personally. The required docs were emailed to Nasreen Abrahams who later later responded via email that both contracts were approved and that she was just waiting on stock. A few days later after an email query from myself she suddenly phoned and advised me that the phone was no longer available and then tried to sell me a different phone instead. She then told me her manager would try and check for phones at other branches. I have not had any calls nor response to my emails since. What I don't understand is why the stock was not checked before wasting my time and money. This phone can still be ordered on the Telkom website.
