Urban Clap — Air conditioner doesn't work and company's technician didn't help

I have booked a compliant with UrbanClap that my AC is not getting cooled. They sent a technician who did not not check leakage but just refilled gas, and he said he changed the capacitor but did not change it which I verified later through ac company technician whom I had called as the ac stopped working after 2 days of gas filling by urbanclap. I had registered compliants and callbacks from UC but response is very poor and no action is being taken. I had paid aprox 8250 to Urbanclap, but my ac issue was not fixed. I had to call ac company technician and pay additional charges to get it fixed. Urban clap cheated me of rs 8250. I want a refund of the amt as the technician failed to fix the issue but cheated me saying he has fixed the issue and changed spare parts, which he did not actually do
