First off, I'm being generous by giving them 1 star! They deserve a ZERO.
I ordered a set of replacement grids directly from their website via an "exploded view" of parts that comprise my filter. Incorrect part was shipped. Contacted immediately via chat: Completely rude and frustrating experience. Chat agent was clueless and was responding from a company playbook with no regard to / knowledge of the actual situation. Customer service is a JOKE. Communication is non-existent. Customer Service insisted I ordered the wrong part -- what a joke -- I ordered it directly from their website.
Box was never opened. RMA department handles all returns and their communication is HORRIBLE (only e-mail when / if they decide to respond -- days go by with no response). Fought with the RMA department for a month before they waived the restocking fee (unopened box), but they kept the $18 return shipping charge in force! The only way they would refund the restocking fee was if I made another purchase from PSW -- Literally held $13.04 hostage until I bought from them again. LAST PURCHASE EVER!
Bottom line: After a month of painful (mostly me trying to get a response) communication, I was charged an $18 return shipping fee -- for the wrong part!
IF you want a complete and utter hassle this is your company. If not, I'd buy from another company.
Pool Supply world is a total JOKE! I will NEVER buy from them again!
