Hisense fridge

I purchase a fridge in October 2017 with a 5 warranty. To date, they came out 3 times to so-called repair the fridge that is freezing up all the time. I contact them again today and still no joy with replacing or refunding me for the fridge. You cannot even open the drawers and they even replaced rubbers which now cause the doors to not being aligned anymore. Game cannot refund me unless Hisense agrees but Hisense just ignores attending to the issue. I requested for a manager to contact me and am still waiting for the call.
