POOR POOR SERVICE GAME GATEWAY!!!!!!!!!!!

Game is such a joke. I bought a Hisense fridge from them in November the unit was faulty and Hisense came out to evaluate the fridge and it was found to be a factory issue and a replacement was required. The replacement unit was delivered to me after a whole back and forth and when they delivered the replacement unit it was again defective. I purchased the unit from Game Gateway and them and their call center also do not communicate as I have escalated this matter numerous times for a month now. Roshni from the call center promised to call me back numerous times and did not and even after the matter was escalated the manager also did not keep to his word. I then now called Game and they have been so unhelpful, I spoke to a consultant by the name of Thabiso, who should not work in customer service because they do not understand what customer service is. After requesting to speak to a manager he put me on hold for 5min and got back to me advising me his manager is in a meeting, with nobody else to escalate my matter to. I told him that I will not release the call until I speak to someone higher up. He then put me on a hold again of 5min-10min before dropping the call on his end. This is the level of service Game is giving their customers, which is totally unacceptable. This is seen as call avoidance and is a dismissal offence is call centers and I hope he gets dealt with. Due to this I then had to call back into the call centre and the next consultant again told me that their is no manager available and that they will call me on Monday. Surely there are other escalation channels?
