Game and Russell Hobbs bad customer services

I logged my complain regarding my microwave that i bought at Game. I took it back for repair and Russell hobbs is failing to assist me as they say i was supposed to register for extended warranty on the day of purchase. I sent an email asking them how will i know how the extended warranty work if i was not informed on the day of purchase by the consultant. I have sent several email to russell hobbs but they are nt replying. The last time i logged a complain here it say Game has responded to my complain but i didnt get any response. Can they please call me on the number provided
