Very Bad Service

This shop i dont understand what is the problem, i thought after my complain few days ago things will change. Now i paid them in order from March/April and even on my woolworths app everything is upto date. With Experian im still on default however all is in order and also having update letters from woolworths. I had to accept that that they dont want to update my credit profile with experian. But now im having a buying power since ive been paying them and even on the woolworths app it shows that i am having a buying power, but now when i buy on the till im being told that i dont have funds in my woolworths acc, however on the finance office shows that i do have funds. Now i wanted the till to cancel all the items swiped since the woolworths card declined, but now their system cant cancel. I must go back to finance office to tel them that the til system cant cancel what i wanted to buy…. And i cant leave the shop now. Now its been 2hours going up & down with woolworths trying to fix my card so that i can go home…. So frustrating! I regret being a woolworths customer …..
