Acumbamail

Bought Tier 3 way back in Oct. 29, 2021, but have never used it (still using MailChimp).
Now that I'm about to use it and I'm considering upgrading to a higher Tier.

But when I log in, I see that my account has been blocked! Pretty wild and not very demanding to invest further in this product.

Do others have a similar problem?
I can also see in here that support is not very responsive. I will still try to contact them and see what happens
