Extremely poor service from Incredible Connection Clearwater Mall

I bought a laptop just before Christmas 2017 at Incredible Connection Clearwater Mall. After a few weeks it started shutting down (or going into hibernation) randomly, almost every 10 to 15 minutes. The windows reports said it was due to a "critical thermal event" which I took to be an overheating issue. I returned the laptop and after a week I received one phone call from them (which I missed ). Nothing after that. The next day I went to the store. No-one knew where my laptop was, has it been fixed or not, nor who phoned me . Eventually after searching a great deal they found my laptop somewhere on a shelf, with no note that it was fixed or not, or even looked at at all. They said they would get back to me the following day. Guess what - nothing. It's now been another week without any feedback from them. I called their customer care line and lodged a complaint against the store. We'll see what happens from here.
