False advertising and unknowledgeable staff

At the beginning of the month, I visited their branch in the Waterfront to upgrade my Vodacom cellphone contract and get an Apple Watch on a Vodacom contract as advertised. I was told by the sales rep that they had the Apple Watch in stock and would order the phone for me. The phone arrived and I returned to the store to collect my phone and Apple Watch and upgrade the contract only to be told that they can't give me the contract at the price that they advertised. I waited for more than an hour in the store while they tried to sort out the pricing of the contract, but only to return home empty-handed. They somehow managed to sort it out that afternoon and I was told that I could collect my devices the next day (though, I still ended up having to pay more slightly more for the cellphone contract as they still couldn't manage to give it to me at the price that they've advertised). Now, almost a month later, I'm told by Vodacom that I can't use the Vodacom OneNumber service to use the cellular feature of the Apple Watch (the only reason why I got the Apple Watch) as Incredible Connection's Vodacom rep did not give me the right cellphone contract. This leaves with me a 36-month contract, yet I can't use the function of the Apple Watch that the Incredible Connection sales rep knew I wanted to use. The whole experience has been utterly frustrating. Even if their sales rep and store manager showed any eagerness to sort out their mess (instead they just pass the buck), it has become clear to me that they lack the knowledge to resolve the issue. I would definitely not return to Incredible Connection for any Apple products or contracts. Not only are they guilty of false advertising, their staff lack proper knowledge and training and simply do not care if a customer is unhappy with their service.
