Pay in full (Not Sainsbury's!)

OldnotDead

took out Zero % CC in 2022 due march 2024, forgot to pay off, Incurred full Intrest charge (my fault) paid off in full Apr 2024, now just recieved latest statement, incurred full Intrest (again), customer support tell me  that I have to pay in full for 2 consecutive months to prevent intrest charges, so if I pay the 2nd Intrest charge, I'll be OK. I've had a credit card for over 45 years, missed the odd payment over the years, never encountered this 2 month rule before, won't again!? Anybody else encountered this ?

How you've phrased it is a bit odd - normally when you make a partial payment on a CC you get charged the interest on the full balance, not just the bit left over which catches some people out. Due to this, even when you clear it, there is always trailing interest (not full interest?) which means you need to pay the balance in full the next month as well (to clear the interest) and then a second month just in case there is anything left.

The 2 month rule though yes is the way pretty much every card works

How much after the due date did you pay the card off? It's possible the balance was then on the next statement meaning more interest e.g. due March 1st, statement created March 7th, you paid April so therefore had the interest from prior to March and then again on the March statement

That's normal. Put a note in your diary next time

Yep, trailing interest between when you paid & when transaction were made.
