I’ve been with Bulb since May 2019, now it’s August and Bulb haven’t taken money from my account. I have contacted them but amazingly they refunded the only statement that I did receive!
Has anyone had a similar problem?

Personally I haven’t had problems in my 18 months with Bulb. Statements are bang on time each month. However if you check other threads on this forum you will find for whatever reason some customers are experiencing problems similar to you.
