Horrific Service Game On-Line

The most horrific on-line shopping experience. Ordered chairs on-line 11 June 2020, The chairs ordered and what was delivered was not the same. I immediately let Game Call Centre know 30 minutes after delivery. In the last 9 weeks I had to make 21 calls, send 14 e-mails and visited a store twice. To date zero resolution despite numerous promises that never amounted to anything. 2 Escalations to management, they promised delivery and exchange on 16 July then again 17 July. That did not happen and have not hear from Management again as they "assumed" it was sorted. Been on the phone today holding for over an hour and still nobody has an answer. Everybody blaming everybody in Game. Tried to go to 2 stores to return items myself, I was told the store and on-line services are separate entities and I can ONLY deal with on-line. You cannot get a person's number in Management and have to go through the call centre and tell your whole story again and then asked to hold for ages. Been cut off 4 times when holding and had to call back again and tell story over only to be placed on hold AGAIN. Not once has anybody kept to a commitment to call me back. All communications has to come from me. I was told by Management should I wish to raise this higher than then I must send an e-mail. I see zero solution insight from Game.
