Micromax Q5 — poor service

Address:

Howrah, West Bengal

i bought a micromax q5 handset about two months a go from "Khushi Telecom" at mandirtala in Howrah, West Bengal and after using it for hardly 3 weeks i found that the headphone mode of the phone is becoming the constant mode and I can't hear any caller's voice without headphone. Immediately I went to the nearest service center at Howrah, West Bengal (A-Z solutions). They informed me that they do not have the spare to repair my handset. They also told that they can give my handset with some makeshift changes but I should not be able to connect the handset. After the arrival of the spare they shall make my handset ok. This will take atleast a week or so.
But after a month also I'm still using my handset without headphone facility. Moreover, when ever I try to contact your toll-free number I found it busy. I don't know when shall I be able to use my phone properly. Last week my local service center even told me that the company is not providing them any spare parts and we, the customers should complain in consumer court. It's a strange reply to me and I'm in complete darkness about the future of my phone.
