Bests & Worsts Reviews from Amazon

I bought this unit from Amazon from Pool Express Group in March 2018. It came on its daily setting the Friday before memorial day and smoke started coming out of the control box and it quit working. I have called pool express 3 days in a row, 1st day I was told the person I need to talk to had stepped out but she would have them call me when they returned. Next 2 days I was told the person I need to talk to was on the phone with another customer but would call me shortly... Still haven't received a call. Their customer service LACKS!!! Their website states they are the only "authorized dealer".
