Liberty Failed to Respond

I have a liberty policy which was not debited. After calling them and getting their answering machines every single call. It leads to one thing and that's to complain about Liberty. This is now my second incident where the debit did not go off. Sent an email to Liberty and as usual no response. Why is the service of the company getting worse each year. Please can someone contact to and explain why my debit are not going off, I'm sure this is a easy way for liberty to use excuses if policies need to be paid or queried. Improve the service and keep up to the name Liberty. Easy to see the advert on tv and think what a good way this company was founded only to find out once with them, another story
