Vitality Device - payment refused due to error entering card number

Hi,

I bought a fitness device from Vitality in may and followed the entire process correctly. However, in typing the HeathlyGear card number from my phone into the Sportmans Warehouse site, I entered one digit incorrectly. My mistake I admit, but the call centre tell me there is no way to rectify it which seems ridiculous to me.

Vitality, surely there is some way to sort this out and pay me out for the device ?

Thanks
