Vodapay BP vouchers being declined and used in another province

i bought a R880 BP voucher on vodapay. they allocated it as a R840 voucher and it was declined. i had to pay with my card. after spending half a night on the vodapay chat support the chat ended without adruptly without any resolution. a few days later the voucher suddenly changed to redeemed. after contacting the chat support again and them contacting BP it became clear that the voucher was somehow used in the western cape. i reside in Pretoria. bp said it might be that is was reissued to someone else. fast forward a few days i buy a new voucher. R880. it gets declined when trying to use it. i again contact the very slow chat support and they can not help. they give me a number on bp with menues i have no idea on what to select. so selected general and after holding on for 20 minutes listening to music and them being very appreciative of my patience i decided to cancell the call.

It is now two vouchers that is unusable. R1600 of my money

My question is why must i deal with bp if i bought the voucher from vodacom and how long must i wait for them to reissue the vouchers. so far this issue has taken up three nights of my time which i will never get back.

i took screenshots of the chats
