Priority Visa Payment Problem

I have recently made payment on the vfs global website for the priority service. However, there were problems with first transaction (the page showed error). I tried paying the 2nd time, it was successful. But more problems arise. I was unable to print or email the receipt as apparently my email id was incorrect(email id is correct) and records are not found. Tried other links to reprint or refund but to no avail as no records were found. According to the bank, there were 2 transactions involving RM744 each. That's huge sum and I was told to email VFS Global but no response from the company.
