Appalling Customer Service

On Tuesday the 19th of January, I went to Game to ask for assistance with my TV set, which has stopped working. The TV set was bought at Dion Wired in February 2019, however although I was sure that it was still under warranty, I couldn't find the receipt. I was requested to provide them with the details of the transaction, and I did so, I retrieved the information from my transaction emails and gave everything to Nomoya at Game Boksburg. To this day, I have received no word. When I follow up, I'm told they're still waiting. Can it really take so long to retrieve a receipt. I gave them everything , even the time of the transaction. this is totally unacceptable as I'm now sitting for 2 weeks without a TV
