Hefty call out fee for ADT technicians

I signed up with ADT Security in October 2021 and I received 2 remotes to activate the alarm when leaving my home. The remotes must therefore be attached to the car or home keys, which I did. As with most keys, they drop from time to time. Unfortunately two different set of keys dropped once and the remotes came apart. I called ADT to report the dismantled remotes because the remotes being in this state means I cannot activate or diactivate my alarm from the outside. When calling ADT, I am told that the call out fee is R636. 47 without VAT and R731. 31 including VAT. I pay an installment of R360 a month for the ADT service, while staying in a relatively safe area. My problem is with the call out fee for a technician to fix two small remotes. When asking why the hefty fee for the call out for a small technical job, I am told that it is for equipment the technician might use during the call out. This does not make any sense for me as a paying customer because the only thing I need is for the remotes to be secured, and all the parts of the remotes are there, just not properly inserted. I am disheartened as I cannot activate my alarm when leaving my house and cannot make sense nor afford the hefty call out fee for an ADT technician.
