Hi Oss,
Welcome to the UK Community Forum and thanks for posting!
Based on the information you provided in your post, it sounds like you are funding your transactions under the direct debit instruction between PayPal and your bank. When you pay in this way, it actually takes between 5 to 7 days for the funds to clear fully from your bank to PayPal. To speed up the process, PayPal pays your seller on your behalf and then wait the 5 to 7 working days to be reimbursed by your bank.
I hope this helps clarify why the funds had not left your bank on Monday 18 th , as this would only have been the first working day after you paid on Friday 15 th .
Thanks,
Maria
