Vodafone India — about my network speed in my area

Address:

Thiruvananthapuram, Kerala, 695584

I have called this idiotic vodafone customer care about my speed of network. It is very hard to even browse through google in my area. The vodafone service is just ignoring the issue. I called them 100 times through 198. I had also contacted them through facebook and twitter. Still they r not trying to resolve my issue. My state is kerala. District is trivandrum and area is andoorkonam (Pin code 695584)
