Terrible service

Their product is not great, but my issue is with call out. I had a problem and they insisted that I pay them up front for a call out and the part I may need and it should reflect in their account before they could even confirm when I could get a technician. Once that was done and the technician had been, I didn't need the part I had paid for. It took several emails and finally threatening to involve the CEO before I got refunded after nearly TWO weeks! I will never use them again.
