PEP is useless stuff, Management and Head Office

Good day last week I bought a R1000 flash voucher at Pep Golden walk Germiston. A few minutes away, I realized my receipt was lost I went back immediately to ask for a reprint, the ladies were rude they told me they don't know how to do it and the manager is on leave for 3 weeks, so I have to wait until he comes back from leave. I did a follow up with customer care, I thought they will assist me to redeem my voucher because flash customer care asked for a serial number, but Pep customer care was twice as much useless as the store I went to were my issue was not resolve They are saying the system cannot show the transaction meaning the system received an unknown R1000, no SKU no serial number and no Token number. I know the system can not be dumb like that, it just being operated by fools who don't know how to operate it, or the want to share my R1000 among themselves.
