I've been using this service for many years without real issue, but something changed this year. Now they block access for no valid reason, and customer service is both not truly responsive and ineffective if they bother to respond. After my complaint, I was suddenly "flagged" for spamming from my account, even though I had sent no emails between the complaint and their "response". I have never spammed anyone. This feels more like a retaliation for having the nerve to complain and not accept a standard form response.
