Jaquar — complaint against bangalore service manager avinash

My jaquar wc was broken with a broken toilet seat hinge. I logged a service request and the technician yakoob sharif said the part has to be replaced. But the spare parts department is refusing to replace it despite hundreds of reminders. There is this area service manager called avinash, who keeps giving fake commitments everyday, but does nothing about it. He then stops answering calls and i have to keep calling from new numbers. Everytime he answers the call from my new number, he stops answering calls from that number again. How many new numbers i have to get to catch this fellow on the phone?
