Are you renting on your Sky box @Haff1 ?
If so, we often hear of customer's credit limits being reset to £0 (not because of anything the customer has done wrong - just so a credit limit can be set up and agreed with the customer )
If yours is the same - it can usually be fixed easily with a live chat to the Skystore support team - but they don't open till 11am
Here is a link for them

Just so you know - if you rent online / Skystore app - you CAN'T send a rental to your Sky box from online.
