Amazon India — no amount credited

Last week I ordered oneplus6 but made the payment online and because of some exchange issues the order got returned. After 2 days i received the message that my account has been credited but the actual balance is not showing up. I again ordered the product today but my trasaction failed bcause of insufficient balance. Have you really initiated the amount? I should recieve call from your customer executive. This is heights that you people didn't even connect to your customer executive then why the hell you hired them when you dont speak make customers speak to them.
