I used the G Suite basic account in the past ($6/month), I was able to get a support ticket responded to within 24 hours. The issue got resolved by someone before their support team responded to me via email, but I was still happy an actual person got back to me.

It's been said many times before, but it's best to pay for stuff, even (and especially) when you can get a good product/service for only ~$5/month.
