Extremely poor service

What an absolute disaster after using them for 5 other services. The lady by the name of Carol is very rude, she knows nothing about customer service. She is a **** and does not know anything about customer service, to think I’ve had good service before and this time was just the worst. Firstly they decided to mess with my bumper, she then tells me that’s how my bumper looked, after she reviews the video she took when I left my car, she’s so quick to ask the technician what happened without acknowledging that she had disputed my statement. Today I decide to check that they’ve stamped my service book, to my surprise, there’s no service book. She claims she mentioned this yesterday, I asked at which point, she said I did not respond, I further asked why wouldn’t I answer, because we discussed my brakes, my light which I specifically told them not to touch. At this point you even doubt whether they serviced my car or not. I am definitely taking this to Motor Industry Ombudsman because even with the manger you can just tell everything will be swept under the carpet
