Hutch Network is so weak

Dear Sir/Mam,
This is mohit from ajmer and i reside at Ajay Nagar where Hutch Network is so weak that whenever i am inside my house, network shows 2 or 3 bars while airtel and BSNL shows full bars and i as a regular and continued Hutch customer wants to continue with it but not with this way. I have complainted many times to them and engineer has also come but he said network is fine but i ahve made him met with two or three people here in locality with same complaint but that engineer did not agree with us. Before sometime i was in delhi and i used to talk with my parents here, there voice was so disturbed that i had to told them that come out of house and then talk. Sir/Mam Kindly HELP ME REGARDING THIS MATTER SO THAT I CAN SIT WITHIN MY HOUSE AND TALK PRPOPERLY AND NOT OUT OF MY HOME. HOPE YOU WILL SOON TAKE ACTION AND HELP ME OUT.

THANKS AND REGARDS,
MOHIT SIPPY.
