Cartrack sucks

I made an appointment device fitting at 12 today. Tilll 1pm, no one came and no call for delay. I called custome care and they said will put me through schedule department but no one answer and just ringing. I called 4 more times but the same. Now 1:50 still no one coming. What is reason make an appointment if they don't come on time, what dose customer care means if they don't care customer ?? This is ridiculous
