I was referred to them by my warranty company. We spoke to them on Monday. Tuesday they called my husband and said they would call back with a date and time. We'd no call, Thursday no call I CALLED THURSDAY EVENING Keep in mind it doesn't take long for a pool to turn green. I called and left a message yesterday. I didn't get a call from them this friday morning so I called again. They stated they were coming out Monday. Really? That means the pool would have been without a motor for a week. And then the lady said we'll call you to confirm a 2 to 3 hour window....now I see why they have the rating they have.....get it together
