It doesn’t look good

https://www.pcloud.com/terms_and_conditions.html

pCloud has a fourteen (14) calendar days money back guarantee, beginning on the day you have submitted your payment for the Paid services. During this period, you are eligible to request for a refund. If you issue an explicit written request for a refund within the fourteen (14) days referenced above, we will process the refund due to you in full within 30 calendar days, counting from the day you have confirmed your request.

We will usually refund any money received from you using the same method originally used by you to pay for your purchase.

In case you have purchased Paid services through a promotional campaign or provided discount, pCloud reserves the right to decline providing a refund.

I just used web archive to check the site on three random days in 2024 and it looks like they always have a promotion and could claim any purchases are ineligable for the money back guarantee.
