American swiss TFG

On Sunday 30.01.2021 I purchased a cell phone from American Swiss Kenilworth centre. Apon my purchase the sales assistant advised me the should there be any factory issues with the phone that I can return it within seven days... To my surprise the very next day the phone starts acting up. It kept on switching off and needed to be rebooted to which the battery would heat up tremendously. I then returned the phone to the store explaining the problem, to which they advised me that the phone needs to go to a technician and the technician will then advise the way forward. When I explained to the sales assistant that that was no what I was told when I purchased the phone she was persistent about the process. I logged a complaint with TFG the next day to which it took them five days to respond to my complaint. TFG's jewelry operations manager then contacted me and advised that they will investigate and feed back to me. To date I still do not have the cell phone and still did not get any response from American Swiss or TFG.
