At one point, Google reached out to me to try and tempt us over from AWS. I had bad experiences with Google support in the past, but liked their AI stuff and was keen to give them another go.
We booked a follow up call in the calendar, I spent good time preparing my notes and requirements for the meeting... and then nobody on their side showed up or contacted me again.
This! They even custom-coded their support portal better than those off-the-shelf vendor like Zendesk. I say this as a Zendesk paying customer.
GCP on the other hand, is a F-tier in support. Almost feel like I need to beg them to get any level of help.
