Refunding overpayment of Assessments

Are HOA Boards, MC's obligated to refund an accidental, incidental overpayment of monthly assessments?

Long story short, The bank our HOA uses to process monthly, quarterly assessments all the sudden has issues with using their site to make payments for us mac owners using Safari web browser.

When I went to make Septembers monthly assessment, I found that the webpage for the bank was freshly updated with graphics, with the update the bank did not retain any HOA account information.
When I submitted my payment, it immediately timed out and I had a pop-up window with an option to cancel the transaction. I cancelled that transaction, I checked my email to make sure the payment did not process. I then switched to Firefox and made a successful payment. Later I saw two emails for payments.

I tried to email both accounting and the MC and received no response. I called accounting only to be told me no they will not refund it. Accounting also told me they were only made aware of the Bank Changes September 1st which I know is a LIE because I called the HOA bank early, 7 am on Monday morning to see if they could kill one of the payments before it posted, I was 20 minutes too late calling them to do so. The agent for the bank told me the MC's were made well aware of the changes more than a month in advance to prepare people paying their assessments.

I am forced to dispute the charge with my bank, which I will happily do, and thankfully I took a screen shot of the cancellation page.

I just feel the MC should take the easy road and issue the refund without incident, What say you?

Ditto CathyA3's response. I'd be annoyed at the incompetence at the bank (HOA?) end but I would also remember that, to me, there are bigger things about which to be annoyed today.

This happens to us and after verified, the monies are refunded PROMPTLY!

Normally I would agree, amid this CV epidemic with reduced work hours and tight budgets there should be no argument and the overpayment refunded promptly.

Keep in mind that an accidental double payment of an annual assessment is different from a monthly one.

Both because of the dollars involved, and because you'd be crossing calendar/fiscal years. That annual pre-payment would have to be accounted for differently and carried on the books until the coming year. It's less work to refund it, and it will make the auditor happy.

With a monthly pre-payment, it's possible that by the time you wait for the pre-payment check to clear, request a refund check and then mail it to the homeowner, the homeowner will simply have to turn around a week later and send the money back. Too much work for too little benefit. And yes, I understand about covid-19 and many people being in financial distress right now - but that won't speed up the process, unfortunately.
