bunch of *******

i requested repairs for my generator and found this company online - though they looked professional and when they came they were suppose to give me a quote before repairs. the guys then removed the control panel and went back to the workshop. they arrived the next day and installed it and not really resolving the problem and were done within 10min. they then give me a bill for 9200.00 without quote or my approval for them to repair the generator .... in short i was hustled and dont want other people to experience the same
