Synchrony Financial Credit Card Complaint

Synchrony Financial Credit card department,

Credit line increase/decrease New York

Today i called my walmart master card because my card was declined when i tried to make a purchase and i didnt understand why. I had a - dollar credit limit on that card, i always make payments on time or before they are due and i exceed the payment amount every time! Well on the - of febuary this year i tried to pay down my credit card and i have been saving my money every chance i get to pay tward my credit card not only to pay them down but also to use them when i need them because i have a 6 month old daughter at home and i am struggling with - income. So to cut to the - i made a $940.00 payment to walmart master card my balance at that time on my card was $1500.00 which should leave me with a balance of $580.00 left to pay on my credit card. I charge $300.00 dollars tward it whoch brought it to $880.00. So now after i had made that large payment walmart decreased my credit line which put me in debt of $500.00 without even notifiying me that they decreased my limit


my balance is back to $1100.00 even tho i paid all of that money because since they decreased my limit and put me in debt it made it as if i went over my limit ( this is how they explained it to me atleast ) i spoke with - supervisors and they - said well the letter was mailed 2 days ago, ok so it was mailed but i never receieved it yet the mail isnt that quick i mean come on! I just dont understand how that is right and am wondering if it is even legal to be able to do such a thing! Three years with that credit card and always on time and exceeding the payment amount every month sometimes i even pay 2 times a month but after making almost $1000.00 payment only then they decide to decrease my limit which resulted in putting me in debt and the over drafting fee which at the time wasnt even concidered over charges because that was my limit! Can they do this. It was like the $500.00 just dissapeared! Please help me!
