I decided to buy the 10 +3 req pack earlier but it came up with an error, not sure of hthe error code all I know is that it sayd "abandoned" next to it and told be to "try again later" However I never received these packs and I still have a pending transaction of £23.99 that I simply got nothing from, is there anything I can do about this since it is my own money and I kinda don't want to waste it on a software error, Thanks, Ucooki1
