Volvo battery replacement cost me double because I didn't know about the auxiliary battery

I'm posting this so other Volvo owners don't make the same expensive mistake I did. My 2016 Volvo XC60 started giving me "low battery" warnings, so I called a mobile battery service I found online. The guy came, tested the main battery, said it was dead, and swapped it for a new one. He charged me 750 dirhams and left. Two days later, the warning came back. I took the car to an independent Volvo specialist and they explained that my car has a dual battery system: a large main battery under the floor and a smaller auxiliary battery for the stop/start system. The auxiliary battery had also failed, and because the mobile guy didn't test it, I ended up paying for two service calls instead of one. The specialist replaced the auxiliary battery and reset the battery monitoring system, total cost another 550 dirhams. Now I'm looking for a mobile service that actually knows Volvos and understands the dual system. I found a company offering Comprehensive Volvo Battery Replacement Service at Battery Zone UAE, and they claim they test both batteries and have the Volvo diagnostic tools to reset the system properly. Has anyone here used a mobile service that actually does a thorough job on a Volvo with stop/start? I'm specifically wondering if they carry the small auxiliary battery as well as the main one, and if they properly register both batteries to the car's computer. Also curious about pricing compared to the dealer. I don't want to get ripped off again but I also don't want to keep paying for incomplete work. Any recommendations from other Volvo owners would be really helpful. Thanks in advance.
