Website bug

I have bought three vouchers online, and I chose the delivery method to be by mobile number, and I have entered the correct number every time. The vouchers was not received on the mobile number specified. When I went online to "My Orders" on the mrp app, I saw that the website captured the mobile number that the voucher must be delivered to, incorrectly all 3 times. For some reason only the last digit was captured incorrectly, meaning the number I specified was 081 *** ***2, but the system captured it as 081 *** ***3.

These order numbers are as follow: 1 ********** 6 ********** 1 ********** 1 ********** 6691

I will appreciate it if you can refund me on my mrp money account for this, as I used my mrp money account to buy these vouchers.
