Poor customer service and handling of complains

On the 26th of December 2020 I took an air cooler back to Game Store Empangeni as it was faulty. Upon arrival there I then did the exchange and got the Voucher. Then my brothers and I proceeded inside to go an look for another item we could buy, we then saw a Sunbeam Aircooler and above it there was a price of R779 and we then agreed to take it and when we got to the till point we were told that the price was wrong it should have been R2599 and they refused to give the item at the price we saw it at. What even made it worse is that the manager became very aggressive towards us and he ended up walking away from us not even saying sorry for the inconvenience. I then launched a complain with their customer complain division on the day day they promised to come back to me on the 28th of December and they did not do and I ended up calling them on Tuesday. Again on Tuesday they said that they will call me before the end of the day Tuesday which they couldn’t do. I called them again on Wednesday same story even today as I am typing this message, they have not called back to tell their side of the story and today it is the 7th of January 2021. “ WHAT A GREAT SERVICE! “.
