Out of stock of deal

I am absolutely disgusted at telkom mobile in n1 city. I went in on the 4th march to apply for the deal 5gb data and wifi device of R99. The lady Philly told me I must wait to see if I am aproved. The following week tuesday my mother found out it was approved and told her I am at hospital she said she will phone me to tell me when to sign the contract. I got no call friday came I called in was told she is not in and they waiting still on stock. I waited whole week for a call I decided to call myself again friday only to find out they not getting any more stock and philly is busy with a client and cant come to the phone. This is unacceptable you cant approve my contract not have stock then let me wait not inform me you received stock and tell me you wont receive anymore stock. Seems as if telkom mobile not interested in making business and yes I am aware that the deal was available to a 1000 customers thats why app**** as soon as possible but before I went to n1 store I app**** at parow and they apparently didn't have the codes for the deal that was the Tuesday and the adverti*****t was monday on the tv.
