Vodafone India — no network connection and bad atitude

I am resident of santa cruz- goa. Being a loyal customer its my duty to inform about the issues facing by me and my fellow colleagues. From past few weeks my dongle [protected] and phone number not getting proper or can say no network the same is been directed to customer care too but apparently without solving they seems to be very busy and no problem solving attitude. sir its not like that in market no service provider whereas they seems to be better please do not direct us to choose them. yours faithfull rajeshbiswal [protected]
