******* with payments

I paid my annual fees IN FULL online in order to qualify for the discount. They are refusing to give me the discount because i paid it through my bank and not on their website. i am a Mac user therefore my browser is Safari. Their website does not support Safari.<br> It does say on the notification that one should pay on their website, but if i cannot get onto it how am i supposed to pay it that way. <br> in any case their practices are discriminatory as they offer a greater discount to those who sign a debit order. Why do i need to sign a debit order? i don't have ANY debit orders on my account because of problems dealing with them when i try to cancel. I feel that i have been discriminated against. I PAID IN FULL TWO MONTHS BEFORE THE DEALINE. How can that adversely affect their bottom line? I paid on the 4th Sep , received confirmation on the 8th so the money was there well before their deadline of end October. Do i have a leg to stand on?
