The Support is Very Bad

I signed up and paid for Yoast SEO Premium.
The installation did not work properly so I asked for support.
Support was very bad. I created a login for them and they said it did not work. Then they simply ignored me for 60 days, not replying to over 6 emails I sent.
When I finally got a response for my refund request, they said they would not because it was now over 30 days.
It is terrible when companies have such poor support. I am out $129. I wish I disputed it on my credit card while I had the chance.
