Iphone watch add-on contract

I app**** for an iphone watch on Friday - 10th of November 2023, with an option to collect at Alberton Vodacom4U store. One the 11th of November, i got an email alerting me that the store has been trying to reach me. I called them back, the call was attended to by Thabiso, who told me to come in store to finish the process of application. This is a top to my initial contract. I ubered to the store to complete the process, when i arrived a consultant called Mathew told me that is not the process and he will call me if they have get stock. Needless to say i spent R160 on a return trip, also moved my things around to go and collect my package to be told that product is not in stock not even at the warehouse. Thabiso is off duty today, he was called to hear his side of the story and there is not accountability from him. I would like my fare refund and also for them to fix this miscommunication an lack of customer service.
