Hello @NiamhShira,
Welcome to PayPal Community Forum and thank you for posting!
I am sorry to know that the funds haven't arrived in your PayPal account. I know how important it is to have funds at the right time. Adding money can usually takes up to 5 business days (Saturday, Sunday, and Holidays aren’t considered business days). If there's any issue with the transaction, the funds will be reversed back to the funding source. If it's been more than the given period of time, please contact your financial institution to know the status of the transfer and I am sure they will be able to trace the funds and help you accordingly.
Regards, Ayesha
