I called back number (07) 5568 6592 reached voice mail of a company called Pure Water Systems.

pure water systems

Caller: Pure Water Systems

Not telemarketers. They provide annual filter replacement service on systems they have sold and installed. We get it done annually on our system. You don't have to replace them, but your water flow through the filter will start to get pretty slow without changing them...

constantly rings to sell water filters even when you tell them you are not interested.

This is where I annually purchase my undersink water filter from.

This is pure water systems. Reminding me about my filter due to change - have only called me twice in 2yrs 1st to ask how my filter was going, 2nd to remind me when it was due for replacement. (I appreciated the kind customer focused service and like that if I have requested not to call until my filter is due for a change they comply).

stop ringing me already I don't want your product
