Payment Refund Request

I have availed a WiFi with a phone line here and have got a new phone for the line. Initially, I have paid around 107.44 for both WiFi and the line. Due to a verification issue, I had to pay a down payment of 421.55 for the phone in order to avail it. I had been noted that the initial payment of 107.44 will be refunded back to my account. It’s been roughly a couple of days and the refund hasn’t been taken place. Requesting to resolve this issue at the very earliest possibility.
