Impossible to make contact with them

Phoned their call center on Wednesday 7th June to withdraw money from a small contract that I've had with them for over 20 years. After waiting on the line for 26 minutes I give up and took the option for them too ring me back. Having now no faith in them I also sent them an email -The email service stated that they would reply within 2 days. Well no one rang me back and no one rep**** to the email. If I had desperately needed the money I would have been in the terrible situation of having no way of getting through to the company that has my money. This is shocking.
