Poor Sales Service

Telkom sells us dreams.. I app**** for a cellphone contract online and got approved, I agreed with the sales consultant that they will debit first instalment before I can receive the phone. Telkom have debited my account, and after that the send me an SMS saying that the phone that I app**** for is 'OUT OF STOCK' they will let me know once its available. its been two weeks and I am not getting any feedback from Telkom instead I get calls from sales person auctioning my application. How on earth does my application still exists if the sale was closed and money have been debited? Telkom kindly deliver the handset by tomorrow 13/06/2018 or pay back my money. even better I will reverse it back on my account.

Thanks
