Cars24 Services — no call back. unprofessional behaviour

Had booked an appointment for a home visit evaluation at 10 am today, no one turned up.. I thought there could be some error so called, i was told i will be given a call back in 15 minutes, no one called, since then i made 6 phone calls and each time was told some one would call back. If you are charging rs 299 for home visit then can cars24 be professional enough to at least call back?? I had to travel by uber the whole day as the car was waiting under my house for evacuation? Will you guys pay the uber fare for the day for your unprofessional behaviour?? Its very sad that i thought cars 24 would be able to help me. But it was more of a mental trauma dealing with cars 24.
Would like a refund of the rs 299 that i paid. Hope this reaches somewhere and not like the phone calls which cannot be trusted.
