FNB dishonoring their own QUOTE & lying about it

On the 21st December I received an email stating that my fixed homeloan had expired. I called your homeloans department on the 22nd and requested a new quotation for a fixed rate i received my quotes by which i responded and ACCEPTED within 24hours has indicated in the email (***) and your terms and conditions.

Later that week i received a call stating the quotes aren't valid because the system is still generating them (which is a lie I requested the agent send me this in writhing) which till today hasn't happened because on my expiry letter YOUR SYSTEM had already recalculate my interest rate.

This morning on the 27th Dec I received another email from *** which a new set of quotes and NO EXPLANITION to the quote I already signed and accepted!

A quote is a legally binding document, which you are now breaching.

I expect someone who knows how to do their job not a consultant trying their luck before I take this further to the ombudsmen's and seek legal advise.
