You need to educate yourself about FinCEN (https://en.wikipedia.org/wiki/Financial_Crimes_Enforcement_N...). You'll end up with the same issue with alternatives, as no business which handles payments is immune to having to abide by the FinCEN rules.

And because Cuba is likely still a country listed as sanctioned, the mention of "Cuban" in the description likely triggered a higher level check to verify you were not trying to transfer money to Cuba via Venmo (which would run afoul of the sanctions).
