Terrible customer service at Game stores Cresta

Today my partner and I went to Game store in Cresta Mall. We were there to buy a dish washer. We walked in looked around and got assisted by a nice gentlemen. We saw the applience we wanted and asked him to procede with the paperwork. While he was still busy with that, we went to check how much credit we had as we had issues with using this account last year. In November last year we wanted to purchase a fridge and a stove, just before we could pay we were told that there are issues with our account. It was the same issue that we had today. the account has credit but we can't buy. Because we had no time to be dealing with Game issues we went to buy at Makro and we had no issue, we paid and they delivered. This time we went back to Game get the dishwasher and the issues that we had in November last year came back to haunt us. Floor stuff was amazing, but the cashier and the "manager " were just horrible. So we get to the cashier, we find that the applience stuff made some mistakes on the invoice that they made, we waited for about 45 min while they were sorting that out. The lady who was assisting was great (She kept on apologising for the delay and the confusion ) as soon as that was sorted, the cashier told us that the card is not working, it has been blocked. This to was very confusing. When we tried to ask her what is the issue now, she just told us to go back to the applience inquiries desk and sort this thing out there, this is not games problem, this is RCL's or something like that. in that shocked state we went back and only to be told that the account was not settled properly, we needed to pay R70. This is what was blocking that account. They then updated my details and gave me a new card and we were told to go pay. Again we walked to the tills and when we got there we were told that there is another mistake. Mind you all of these people who are suppose to be assisting us come across as if we are bothering them. I remember this was the same thing that made us go to Makro last year. The lady at the appliences inquiry desk needs to improve her customer service same goes for the cashier and the so called *********** manager that was called to assist and disappeared need to fix their attitude at work and also their customer service. In total this should have taken 20-30 min but we ended up spending over an hour and a half and still we were not able to buy what we needed. I can tell now, I will not be going back to face that incompetance, I would rather try another branch or another store like Makro (maybe they will take us serious)
