Been a member for almost 50 years and whilst Nationwide's service is generally good, there are some frustrating aspects that need attention.

My previous Flex Regular Saver Issue 3 account at 6.5% has ended and Nationwide have informed me today that the money has been transferred into an Instant Access Saver 10 (Issue 3) account at 1.70% which it has. I have looked round for other accounts offering better interest and noted they offer a new Flex Regular Saver account (Issue 7) at 6.5%. But, when I apply it says that I can't open it as I already have one Flex Regular Saver. But, I don't and Nationwide have informed my in their email that I don't!!!

Having entered into a Chat with them I'm told that "You can only have one Flex Regular Saver Account at a time. Once it matures, it turns into an Instant Access Saver with a lower interest rate. After 2–3 working days, you’ll be able to open a new Flex Regular Saver Account with 6.5% interest for 12 months. Since your account matured yesterday or today, you’ll be eligible to open a new one in 2–3 working days."

BUT, Nationwide wrote to me to inform me that my account has ended and given me three options, one of which is to "Choose another savings account with us". So, why when I try to open another savings account it doesn't let me. Are their systems so antiquated that they can't tell that my existing Flex Regular Saver no longer exists and therefore I should be able to open a new one. Why do I have to wait "2-3 days" and presumably keep logging on to find when I can now open one.
This is not good service.

And the response from Nationwide (see below) says "you'll need to wait until the day after the account has matured before you're able to apply for another of the same account." So, why wasn't this communicated in the email Nationwide sent out giving me three options, one of which was to invite me to open another account? An easy and straight forward solution.
And their complaints page gives me unsatisfactory options including i) Chat (I want to speak to someone with specialist knowledge of the issue not a generalist that will apologise for my inconvenience but not address the root cause (a poorly communicated email) ii) writing a letter (at my expense when I should simply be able to send an email as Yorkshire allow you to do).
