Bad service, no technical support

Worst petrol station ever, no customer service,they don't care, I purchased a BP fuel voucher worth R440 through Vodacom drive to 3 bp stations who say they offline and they don't do vouchers finally go to BP opposite Greenstone Mall they say the know how to redeem the voucher but ask their colleagues for help, they manage to put in the voucher but it declines, the manager tries it still declined, I get turned away to sort it out on my own, I spent 2 hours using up my own airtime phoning Vodacom and BP customer care the problem was with BP their system is having issues with the R440 vouchers, they tell me to send a email which I did, with no turnaround time I am stranded without fuel cause some people like me get paid last day of the month, when will I get a working voucher, I have no idea?will I ever get compensatiled for my inconvenience as bp system issue has costed me much more for what I have paid for my voucher,i doubt so, end result BP garage is not worth supporting,rather give the business to campanies who care.
