Coinbase customer service is lacking

I opened an account with Coinbase in 2014 as part of a promotion to offer $5 in bitcoin to new users. I cashed it out as soon as the bitcoin hit my account. Had I held onto it, the bitcoin would be worth over $1,000 today. 

Because I used an old email address, which I don't have access to any longer, I can't log into my account. I emailed Coinbase and got a "We received your email but are currently busy with an influx of new support requests. We will get back to you in the next few days." That was a few months ago and I haven't received a response yet. 

For that reason, I decided to create an account with Gemini. With 2FA and lots of security, I feel safer using Gemini than Coinbase. How has your experience with Coinbase been?
