Vodafone India — recharge

Address:

Palakkad, Kerala

Sir my phone no is [protected]. Before one week i have recharged 196 rs from my vodafone app for 28 days all free call. But today it call facility is not available. While i contacted with customer care they told, that facility was for one week (1000 min). What should i do because that offer was for 28 days but no call facility is available today
