Worst customer service ever

I booked an air con service and when I got there on the agreed date was told that the machine broke down and i was to be booked again which will be free for the inconvenience …two weeks later a got a call to come on the 22/01/24 at 10:00 …I got there on time and after waiting 30min was told that the technician is not on site and his stand in can’t operate the machine and will get a call on when to come again…. Do keep in mind that I drive 35km to get to brits so it’s 140km wasted in total and my time
