[Resolved]  Prepaid — World calling card blocked.

Address:

East Delhi, Delhi

I am a regular user of Vodafone World Calling Card for the last more than two years. Calls are particularly to Australia where my son resides. My mobile No. is [protected]. Last week I purchased the WCC of the denomination of Rs.375 as usual. It was regisetered also bearing No.[protected] and reflects a balance of Rs.339/-. However, when I make a call to Australia the response is "your card has been blocked. For further information contact customer care service at 111. A number of complaints had been lodged within 111 but they have not been of any help. I also sent SMS at 6790 which replied "we appreciate your feedback. Thank you". However, it is more than week, I am not able to use the card as every type it is repeated that "your card has been blocked". Of late my contact through 111 has also been blocked.
I do not know what to do. Could you help. Needless to mention that Vodafone had been manupulating bills while I was post paid customer and had to shift to prepaid, retaining the same number.
