BSNL — Weak Signal problem

Address:

Thiruvananthapuram, Kerala, 695007

Sir/Madam
I am staying at cheruvettucad near sangumugham, Trivandrum since last 12 years. It is very regret to inform that not a single day I got a successful communication through my mobile which is with a Bsnl connection. Always signal bar shows like waves..no strength. Talk breaks repeatedly. Minimum 5 try for a communication due to break while talking. Browsing is not at all successful, very poor. I do pay monthly prepaid since last 10 years. Tell me bsnl do I want to keep ur sim for future use. All other operators having towers near to me. Why BSNL don't look this matter seriously.. I pray please do something to solve this freqent problem...
