Bad Bad Bad service

Hisense products are bad, this is the second time I am writing a review but this time its for my FRIDGE!. I July I logged a job for my fix to be fixed as it was no longer cold. On the 4th of August a Technician was sent to check & fix the fridge. He said that the gas is finished and that something was blocking it. The was was filled, now we are in September and guess we have the same problem again. This time a different Technician was sent by Hisense and he even arrived late at night. He did the same thing, he filled the gas again. Today my fridge went from bad to worse as now the ice is melting. Clearly these technicians don't know how to do their jobs. Instead of fixing the problem they made it worse than it was. If it is not the TV its the damn fridge. Now they want to send the Technician again and mind you this will be for the third time.
