Vodafone India — money deducted from main balance without proper notice

Address:

Chennai, Tamil Nadu, 600075

I had recharged my number with the offer of 70 days unlimited calls 1GB per day at 5.20 PM on 1/21/2018. After recharge i received an SMS that the plan is active for the same offer immediately which is 5.21 PM. As soon i saw the message i made call to my friend. Around Rs.15 deducted from main balance.
Called up customer care he said plan is active after 5 minutes only. But I received the sms telling plan is active within a minute(Attached the screenshot with time). Very unsatisfied answer. His name is Dinesh. He told he will transfer the call to senior officer. But looks like he just put the call on hold. I waited for some time no response.
