Im so disappointed

I just got off the phone with Discovery,stuck at a petrol station due to their dishonesty.I'm stuck at BP just poured petrol and swiped my vitality drive reward card to pay for the petrol and it said the pin was invalid...this card i recieved from you telling me its loaded with how ever much has now got me stuck at the garage because i believed your consultants...I am now waiting at the garage as we speak in the dark waiting for someone fro. Krugersdorp To come and pay for my petrol which I would have likely not poured had I not received this card....I then I<br> call I speak to a consultant who tells me she just spoke to someone who will reset the pin I'm still waiting.I know it's Friday and everyone wants to go home but as a customer I really deserved some sort or honesty from my insurance company...As a customer who had nothing but good things to say about you company you have really disappointed me..
