I'm trying to set up a website for a client through WordPress.com. I quickly realized I made a mistake. I found out I could only use my custom theme when using wordpress.org or an external webhosting service. I chose the latter. Unfortunately I had already purchased the bundle upgrade (99 USD) after I found out about my mistake. I asked for a refund and according to my Paypal account, I have already received my refund. When I check my bankaccount, I can NOT find the refund. Something's gone wrong. Could someone from WordPress please look into this issue?
