They give no refunds .bad mangement

I purchased a product yesterday and I refunded it today as it wasn’t the right thing we needed for the tv we gave it back in original packaging as well as with the slip they refused they said they don’t give any refunds what so ever to any client .they don’t have any signs up in the store to stipulate this one is it on their receipt .there after the manager has so much attitude manager by the name of Mack he said he didn’t tell us to buy the product there it isn’t his problem ! Such a disgusting store wouldn’t recommend anyone to buy there
