My order was paid partly by Paypal balance and partly by debit card. The limit for debit card charge is 120 days and I ordered in August so that's past. Paypal haven't asked me anything as yet; I don't know how to contact them if it's beyond the 45 days.
So I have asked for a refund, given them 14 days and said if no response will use the UK small claims court (not sure if this is really possible but I'll look into it later).
