appliance repair team

My Bosch dishwasher stopped working. The technician diagnosed as a motor problem. Asked a half of part fee and labour. One week later the same technician came and installed the new motor and said done. I was not there and my family member thought the repair was done. NO! Once we tried it to run, the machine didn't stop at all. We had to turn off the breaker. I called the company and they said we need a new control board. They demanded a half of the cost of the part. I was confused and paid the money. But after all no follow-up and I called again and they said they didnt know when the part would be coming. I had to ask another company and finally fixed it.
