I have been going back and forth with obtain the correct replacement item for a malfunctioning thermostat. After having to paying a security deposit for a replacement due to my thermostat not recognizing any WIFI. I now have received the wrong color. I have made numerous calls and emails with no resolved. I have provided all required serial numbers and pix to confirm the product I have. All the while the time is ticking by in which I need to return my defected item (within 21 days ) in order to get my security deposit. Please help on how to get this resolved. This has left me more than frustrated, unheard and angry for what seemed to be a simple fix for an item that is still under warranty. I am currently on the phone waiting yet again for which I have little to no confidence this will be resolved yet again.
