misplaced voucher

I purchase a toptv voucher on Saturday 25/07/2015 which I misplaced. 26/07/2015 I when back to the store at which I purchased it as requested by supervisor Moe at the call centre to get a copy of my till slip and emailed to [Email Removed] on the 26/07/2015. I called many time today and I was unable to speak to the supervisor, I was told that by the manager of the store at which I purchased the voucher that Toptv is unable to credit my account for R279 as I did not have the serial number. I have email a copy of the till slip. Please can you help resolve this matter as I budget this money on a monthly basis. <br> Thank you<br>
