Europ Assitance SA MiWay Roadside assistance

I called MiWay to request assistance with a flat battery, they took too long to assist and I got assistance from someone else. Europe Assistance is the company outsourced. Gavin called me to say they are going to send someone to assist me and I told him I had already received assistance and He said He would cancel. I then received an sms to say I have lost 1 of my roadside assistance call out for the period. No one assisted me and they say they have paid the people they had called so that is why I forfeit my call out. This is strange that they paid someone for doing nothing as I told them when they said they were going to send someone that I had already been assisted.
