Failure to disclose terms and conditions on point of sale,ill treatment of consumers

I bought a Samsung microwave at game on the 4th of May 2019,on the point of sale l was advised that it has a 1 year warranty .I used the microwave till the 1st week d December ,it wasn't switching on.I called game they told me to bring it in store,i sent it in by the 12th of December 2019.i was advised the suppliers had closed and they were only coming back January. On the 2nd of January l received an sms from Samsung acknowledging that they had received the microwave.i waited for 2 weeks there was no communication,i then called game to find out,they told me they had a quote from the supplier when l asked why ,l was informed that because there was an infestation from roaches and it wasn't covered in the warranty,l then called Samsung spoke to a lady by the name of Muriel who informed me that the problem was the electrical socket l was plugging my microwave on and it was not covered.i informed her that l didnt understand as game had told me its roaches,She tranfered me to Petros the technician who furthermore testified it was roaches.The consultants told me there was nothing they would do for me ,and l asked if my matter could be escalated to the manager.The manager called me back,he just wanted to tell me about their terms and did not want to hear my grievance a s a customer,he ended telling me that i bought my appliance from game not Samsung,i wasn't supposed to have called them as l was contradicting my self,that was on the 25th of January 2020.On the 27th in the morning l called Game to speak to the manager Gladys,l relayed the matter and what had transpired between me and the technical manager at Samsung ,she said she was going to do a follow up and call me back.Since then she hasn't called me,l've called twice all to no avail as she is unavailable .Today i spoke to Daisy who rarely gave me a chance to respond to what she was saying to me,I told her that on the point of sale l was not advised that there certain things that were not covered and so on ,She told me it should make logic to me that infestation was not covered.
