Business ProfileforCosmos Electrical Co

I called Cosmos electrical on September 11th to repair the exhaust fan in my condo unit. The lady said the service fee will be $200+ and the motor fix will be $400 and I agreed with that. Later in the same day, John called me. He stated that the fix for the motor will actually be $1200+ instead of $400. I was super confused at that point as he started to preemptively think that the motor is going to be the issue - which indeed turned out not to be the issue later. I said “Well, it does not make sense for you to assume the motor is actually the problem, how about you do some inspection first and let me know. We can work from there”. Also, as since I will not be able to accompany the fix myself - As the unit is being rented out. I sent a message to John the same day “I wont be there myself tmr but my tenant will be helping with all cases. You can just call me when we reach out to any decision points.” For the repair day-Sep 12th.To my surprise, I did not get A SINGLE call that day from anyone at Cosmos. I had to call my tenant myself at 2pm to check with what’s going on there. He told me that the repair worker had already left at 1pm. I am utterly confused at this point as I thought they were supposed to reach out to me during the fix to make some decisions on the moves going forward. Then I gave a call to John immediately to ask what’s going on. He then called his worker and literally just threw a random number to me “yeah, it will be $900 you know?” At this point, I felt robbed as the fix was completed without giving me the exact cost upfront. Also the issue does not match to anything we have discussed prior and he can technically throw any number to me at this point. Then I called John to ask for an invoice with a detailed breakdown of the work. Two days later, I got the invoice from Cosmos. And of course, there is no detailed breakdown of the work. It just stated that “the entire work is $900”. I have already paid the service fee but not the rest.
