Effing banks and their credit cards, man.
Please “eli5” me this and how it makes sense:
For my cc bill due at the end of August I mis-keyed the payment amount and ended up getting an interest charge shown on my bill due at the end of September. I always pay the full balance due to avoid interest, but I messed up this time. When the rep made me realize the mistake I made, she volunteered to remove the interest charge (8 bucks and change) so I said fine.
Despite the reversal of that interest charge, out of an abundance of caution, I actually paid the full balance shown on my statement on or before the September 27th due date. To my dismay, I get my new statement yesterday, generated after that payment, and now there are 12 more dollars and change to pay as an interest charge (8 and change of which were somehow covered by the previous interest charge reversal, but still).
WTAF? What happened to “Pay full balance on statement by due date to avoid interest?” Am I now locked in some bizarre cycle of paying interest forever till the end of time because I mistakenly paid 20 bucks less than a full $750 balance once?
