RANKIN PUMP & SUPPLY

I have an RO filter from Ecowater that we inherited from the previous owner. Rankin charges about 300 dollars to change the pre and post filter annually. They also include a service charge of 75 dollars if they come to change the filters. This time I decided to change the filters myself since I was finding them online for 100 dollars. The online vendor also talked me into changing the membrane and when I changed everything there was a small leak in the system in addition to a leak in the membrane. I was contacting the online seller about another leak in the membrane and I contacted Rankin to help me with the leak in the system which they agreed to do. The plumber was nice and he was able to fix the leak but in the process, somewhere else the leak started that he promised to fix. I was trying to deal with the online seller about the membrane and the seller wanted to talk to Rankin since they were working on the system. After they both talked, Steve at Rankin became very mad at me and never sent the plumber to fix the leak that was created by his plumber. He was very rude, shouting on the phone and even put the phone down on me! Something that I have never experienced before from a business. They sent me an invoice for 150 dollars that I refused to pay till they fix the leak created by his plumber. They are very expensive and the owner Steve is extremely rude.
