Student Finance Historic Fees

Hi,

Has anyone experienced the following?

Graduated from University of Birmingham in 2011 after studying for a 4 year undergraduate masters. Recently paid off my student loan.

Now, 13 years after I graduated I've received a revised offer where Student Finance England have paid the UoB an additional £3k for my fourth years fees. Which they're claiming weren't paid to the UoB in 2011 due to "an admin error".

Obviously this is quite alarming, because, SLC are now looking at restarting (yes!) my student loan deductions, which I've not paid for some years to recoup this loan. My balance on the online SLC has also increased from £0 to ~£3k in the last few days.

To add insult to injury, the interest rate now sits at 6.25% instead of the much smaller rate I was paying several years ago!

Has anyone experienced this before, and does anyone have any advice on how to deal with it?

It feels likes it should be statue barred due to it being over 6 years old.

TIA.
