Bad customer service at Game Paarl

We bought an smart watch at Game Paarl last week, opened up the box yesterday and the watch didn't go on... Decided to take the watch in today for them to show how the watch must be turned on, upon checking the lady of which is the floor manager is saying that the watch was broken by us... My fiance told her that we didn't do anything besides switching the thing on... The floor manager is arguing with a client that the client broke it, what kind of customer service is that, arguing with a customer and that coming from a manager... If this is the type of service that our people are getting from that store then I'll advise everyone that I know in Paarl not to purchase from that store... Not to bring race in to this but if it was a customer of different colour, the service would've been different... I'm going to drop the watch in the store and leave it there... The floor manager or store manager can take the watch for them....
