1Voucher is nothing but ****, they sent vouchers which are used already and they fail to credit or refund my money, one must never ever purchase from from 1 voucher they are nothing but ****** pathetic ****ers its. I have bought R150 voucher and received a used voucher but nothing is been done by the useless agent to resolve the issue what kind of a company is this, we need to open a case of ***** against 1voucher I'm sure I'm not the only one they ****med.
