Disappointing Service and Not Adhering to Important Instructions

I feel disappointed that I should even be writing this poor review as I generally like Specialized Stellenbosch and the staff are pleasant to deal with. We've also purchased many bicycle-related items from this store and it's usually one of our happy places. However, it has the opposite effect when we explicitly instruct them not to move my bike settings when taking the bike in for a service and they seem to simply ignore that important piece of information. I have serious back issues and have a custom-fit bike. I have my bike set up checked about twice a year as it is imperative that my set-up is correct to avoid affecting my spine negatively. I explained this to the staff member the first time I booked my bike in for a service and the instruction was not adhered to. I had to go back for another set-up after that first service, which is an unnecessary waste of time and money. The second time I took my bike for a service about a week ago, I explained the situation again and my husband also went back and explained the importance of the mechanics not moving my set up BUT again, I got my bike back and was in severe pain after a few kilometres of riding the day after they serviced my bike. I could feel they had messed with my handlebar and grip settings. We rode to the store and my husband spoke to them about our disappointment and their bad service in moving my set-up but they said they hadn't changed any settings. This denial is rather annoying as I had cycled hundreds of kilometres without pain, one service and I felt the difference in my settings immediately. This week I had to go to a chiropractor because of the pain from the change in my setup and I had to go back to the guy who does my bike set up and he confirmed that my handlebars had been moved to the right by 6 mm and my right handlebar grip was rotated by 3 mm, which confirms the reason for my discomfort. Again, this cost me time and money which could've been avoided had the guys at Specialized Stellenbosch paid attention and cared enough not to move my bike settings during the service. We are now going to try a few other bike shops for future services instead to try to find one that cares about the client's comfort on the bike and pays attention to important instructions.
