Bluedart — Payment issue

I had received an order fro a power bank, the other for which I had placed through Amazon, from Bluedart and it was a cash on delivery order on June 14. I paid through Google play using the link the delivery guy sent. The first time i Paid the screen went blank so I paid once more using the link. But the issue popped up so I sent the money to the delivery executive. However, when I went home and checked my bank statement my money had been debited thrice. I tried to call them but they don't have an option to speak to someone. I sent two emails and it's still not resolved. I would like my money back for the first two times or from the delivery executive as well. The delivery executive's number is [protected].
