Device not available as promised by manager

Went to Telkom in Greenstone (on a Wednesday) to apply for a contract after my phone was ******. As I was going on holiday out of the country the following week, I asked the sales person (Tom) if it was possible to get the phone before then. Tom asked the manager who confirmed I would have it by Friday that week. After the confirmation, I app**** for the contract. I called the shop a couple of times the following day to check on the status BUT there was no answer, I then went to the shop and I was assured all was in order to collect on Friday. On Friday, I was told the manager called the courier company that was supposed to deliver the phone and they were on their way. I waited over 2 hours at the shop until I had to leave as I was going away for the weekend, we agreed that I would collect on the Monday. On Monday morning, the manager was suddenly not interested in attending to my matter, she never gave me a second of her time. After waiting for over 2 hours again, I was told they were out of stock! Nosi was the only person who assisted me. The manager did not explain what happened to the courier company that was on their way on Friday! Had to go without a phone! terrible service!!
