<human>: Can you give me a shortened version of the text?

It's a store card (I know, store cards are eeeevil but it's the only way I can use my employee discount). Last month my bank screwed up, send an electronic payment and a check, and then cancelled the check (so it couldn't be cashed). I called the company twice, once when the bank let me know the check was sent (to tell them NOT TO CASH IT OR APPLY IT TO MY ACCOUNT) and once when the morons tried to cash the check, to repeatedly tell them not to (they did it anyways and I got a $25 fee for insufficient funds or some bull like that).

Anyways, I made my payment for March in full on Sunday. I had an available credit limit of like $20, which seemed strange because I had payed off the entire thing and my statement balance was nowhere near my limit, but okay. Monday comes by, payment has posted, credit limit did not go up. Tuesday, credit limit still did not go up. I called them (since I had to go shopping that day), they told me because of the 'insufficient funds' that they will either a) wait until the statement is updated/goes through/they get an update from my bank (three different people gave me three different answers) or b) i call my bank with them on the line and get someone to confirm yes, the payment was posted.

I wasted fourty minutes and almost missed my class trying to sort it out yesterday. I called them again and they gave me the same spiel and that if I decided to wait my available credit won't be updated until the 13th- two weeks after paying off the entire balance. I'm tired of waiting on the phone and having to input my social and my PIN for strangers. I'm getting really irritated because I'm expected to go to work and talk about how GREAT this card is and how it'll solve ALL your PROBLEMS and yet the past month has been nothing but a headache for me involving it.
<bot>: CC company is refusing to update my available credit because "the payment hasn't posted" despite it showing as posted on both the site and the bank. Call center is being extremely unhelpful. Is there anything I can do?
