Truecaller — charged twice for premium subscription

I'm premium customer of truecaller from 2018 (June).
Yesterday on 4th june, 2019, i was charged ₹270 and again today 5th june, 2019, ₹270 is deducted.

Please help me in getting my refund of ₹270 which was charged twice instead of once.

Mode of payment was credit card.
