GAME GATEWAY Horrific customer service

My fiance and I bought a fridge in December 2019 and were told that when we are ready we can pick it up. We were meant to get married in April so we said we will pick it up then but due to lockdown that didnt happen. In July we went to Gatway Game and the lady said we must come back as they need to contact head office because they changes systems. We went there 4 times and got nowhere. Someone else started asked us to leave our receipt copy and they will sort it out, they've had it for over a month and we've been to the store another 4 times to find out what going on and he says it's with his manager....this is going on for 3 months!!!! We dont event want the fridge anymore, we just want credit. Such a big establishment but such poor service. The way they make people run for their own money is disgusting. There is absolutely no sense of urgency.
