Thanks for coming back to me @Calendar44, my advice would always be, be careful what you read online - most people posting about a service will likely focus on the negative experience, rather than posting to say how good our services are - which of course also extends to other providers and services too.
Are you currently set up with a new provider?
If you are, or when you are, we'd be happy to assist in making the number port as smooth as possible for you.
Kindest regards,
