Very bad service

Took Ford figo for service, only needed service and checking of headlight. Got a quotation of R21k, a cracked windscreen which is taking forever to investigate. I have a new battery quoted an fitted on by technician who didn't even comfirm with me that can they change the battery an now the battery light is on and I cnt drive the car and no one seems to care. Very bad service I received from that branch. Had to sleep outside my home as my house key was in the car, because they decided not to pick us up when we were fetching the car, we had to get the car the following day. What is upsetting is that I was the one who was keeping tabs on them
