Kent RO systems Service Centers are frauds and cheats and they will close your call as routine visit and then charge you for parts and services even if your product is in warranty and sometimes their technicians will not provide bills for products inspite of repeated requests and service center owner will question you for not taking bills instead of questioning his employee.
This seems to the practice of service center to dupe Kent and Customers by closing legitimate calls as routine visit and sell parts and service separately.
The only way to use kent RO is to make sure you know about each and every part and their how to find that the part has reached its end of life. Else these cheaters will cheat and rob of your hard earned money.
