B&G TV Repais ****MERS

This place ****med us. They came to fix our tv. Quoted R1,100 them sent an invoice for R1,650. We paid and they said it was more because they had to replace the main board and repaired the power supply. It still wasn’t working. Then they came back and said they taking the tv in. They said they would inform me the following day when the tv would be returned. After that they went radio silent. I can’t get hold of them telephonically or via email. It’s been a month.
