Horrible Customer Service!
I ordered 4 replacement filter cartridges for a Quad DE 100 on their website. After one week, the items were in stock, but stuck in the final stages of shipping (according to their order review and customer service rep). I spoke with the customer service rep who told me it takes over a week to ship an item and 7-10 business days in transit. When I pushed back on a standard 3 week delivery timeframe, the customer service rep told me they were sorry the order couldn't be "received by your standard time frame". Three weeks isn't my standard time frame, that is well above industry standards. If I had purchased through Amazon, I could get the item in 1-5 days... not three weeks. I was expecting 1-1.5 weeks. LAST PURCHASE EVER from PoolSupplyWorld.com! I will NEVER buy from them again!"
