WAC Petroleum Service WORST

Worst company I have ever worked with. I bought refurbished pumps from them and on delivery and installation it was not working correctly. After complaining to them they indicated that they did not install them and even though I had a six month warranty (not Subject to them installing them ) they made my life he'll and would not want to attend warranty callout without payment. Products was delivered late and never answer any calls. Rude and not willing to listen to anyone.
