Dissapointing service

I purchased a Pes 2016 game online and opted to collect seing as it was a public holiday. When I got to the shop they explained that it had not been processed yet which I accepted as it was a holiday. The next day I received an SMS saying I can collect the game and I went on to call the store to confirm my order was ready, and the manager said it was ready I can come. When I got to the store I was told that they can see the order but I can't take the game because my account has not yet been credited and the entire head office is on leave therefore no one can assign the money to my account. I showed them the SMS and the email I received which shows that I had paid but the manager said there was nothing he could if the money is not assigned to me. Now I have to wait for the head office to open on Monday and after being assigned come back to the store. I have made 2 trips and yet another to make, so I can collect the game whenever they decide to process. The store is 20km away from where I live. I can't cancel or ask 4 courier service because the head office is closed, what sort of business is this anyway? Very dissapointed and I will never use bt games ever again and neither will an
