HI, moved house in March and due to a bunch of issues, I didn't get my internet working until last month, as a result, I've been given £910 credit which will go on my account for my next bill, which should be tomorrow. Is it possible to either add more credit myself into the account and use it to buy a device (iPhone 17 Pro) or get the credit refunded to my DD payment method, as I don't really want to use the credit to just forget about my internet bill for the next 18 months
