*********** . No customer satisfaction ,Huge DISSAPOINTMENT

I brought my 55 inch Sinotec TV from Game at Bloed Mall by Sep 2019,Last year Oct 2020 the remote stopped working and i still couldn't control the tv manually so I went to game and ask if I buy new remote I was told they don't sell universal remotes .So i decided to take it to game customer care service to help but i lost my slip so I provided them with my bank statement with shows that i brought the tv from them....I was told to wait at least 3/4 weeks for them to track my slip after that waiting duration no one contacted me ,now I went to game store numerous times hearing the same story over and over again that they cant find it in the system before I know it .... its December am told that the tech department is closed I will have to wait for them to open .Come Jan 2021 Maria the Senior of Customer service whom has been telling me story for such a long time ,tells me to RELAX tech people will call me when they are done with other peoples home service .Today she calls me again to ask for a serial number of the tv which i don't and trust me we have been through that story before last year ,now I asked her since i can't be helped i would like to be refunded my money back and she says she doesn't think its possible .........I Mean what is the use of the Warranty and Guarantee we are told about if we have to go through such ,they are so *********** ,unprofessional and the is no customer satisfaction

Now what do i do from here on because clearly Maria knows nothing .I WOULD LIKE TO REFUNDED AND GET RESPONSE AS THIS IS SUCH A DISSAPOINTMENT
