Tech Geeks - Extremely poor customer service and falsely advertised products

We bought the "TG Flex Android Box - Netflix Certified, Disney+, Primevideo supported" from Tech Geeks on Take A Lot which worked perfectly for a few months. We then bought another one which also worked fine. Now all of a sudden we are unable to watch Netflix and am getting errors on other apps which worked perfectly previously. We requested their assistance, on which Joe Stevens, the customer relations manager rep**** on how to fix the error. This did not work, another email was sent and he rep**** again with a video on how to fix the error. Still had the same issue and now no one is replying to us. We are now sitting with two of these boxes not even a year old that we cannot do anything with. They do not have any other preferred contact method. Their client service is extremely poor and the products advertised does not match with the spesifications.
