I called to Northstar Mechanical and asked if they could come and check my heating systems. The representative said that they would need the deposit and they have asked me to pay it to the repair man, because he would tell me what else I needed to pay for the repair. The repair also asked to pay for some parts and job, so I have paid $5, 000 and the repair man said that $3, 000 was a deposit, which would be returned. But after the systems were fixed, the rep hasn’t refunded me.
