Vodafone India — Not restoring my balance data

Address:	Kolkata, West Bengal, 700075
Website:	Vodafone services

I avail a plan of 999 postpaid with cug connection. My data pack is 10 gb. On 10 the of april i had given a mail to rahul tiwary that how is it within 10th april my 9 gb has been used. After checking from the system rahul tiwary gave me a mail on the next day that with detail usage of my data. Astonishingly only 4 gb of my data has been used. There was no explanation for my balance data. Several mail was given to restore my data. But till now no data has been restored. Until and unless u restore my data no bill will be paid further from my side.
