Was with Vodafone for last 2 years. Never had such bad experience with Vodafone but from last 4 months I faced unrealistic experience. Signal was weak at my location, bad calling experience, complaint at Vodafone Store and Customer Care was registered but nothing happened. Recharged several times with roaming pack, but it always failed. No one at the Store knows what the issue is. Switched to postpaid but had worst experience with that too.
