I have taken 2 years kent ro amc from apex but theae guys are frauds.. They charged 11500 for 2 years amc. They promised every rhree months services with candles and filter change and every 8 months membrane change. They promised us that we dont need ro call them. They will come in time. After calling them times and again they will come at odd hours with lots od excuses. Its going to be around 2 years and amc is to be expured thwy did not change the membrane and hardly came four times for services. Please dont go for the trap. Rather use kent original website for complaints and amcs. Im following since last three days to change membrane of my ro but they hardly respond. The girl who picks the phone is really smart asked me to renew the amc in dec so she can change the membrane. With 3 more months of extension.
