Worst credit solutions company EVER!!!!!!!!!!!11

I had an arrangement in place with Nimble to pay off my W credit card over 6 months as i had received a discount from them, i paid the first 4 months on the 5th month i called in to let them know i have an issue and wont be able to make that months payment but in the 6th month i will settle the account for both months (5 and 6) now that its the 6th month im calling in to let them know that i want to settle since im still within the 6 months period, they refused and said i will have to make another arrangement and will have to settle the enitire balance cause they get the instructions from Woolworths, i called Woolworths to explain my issue and they said they don't have any control over that account anymore cause its been sold to nimble, they have no authority over it, so that means the agent manager **** to me.... these people don't want to help us shame!!!!!!!!!!!!!!! i have been the one taking initiative in calling in and even when i had the issue i explained to them... i am still within the 6 months arrangement but now they don't want me to close it! very sneaky those people!!!!!!!!!!!!!!!!!
