Useless customer service

I have never been so ill treated by a retail store and I at a position that m closing the account...I paid Woolworths during Easter holidays r1500 and my credit was r2009 and I shopped for my essentials wen I produced the Woolworth card for payment it declined and advised my payment will only reflect after 48 hours,what an inconvenience n I asked the lady is that...few days later I called the head office and I was told my card is fine I can shop...I could not benefit on the buy 3 n pay for 2 special for kids...today again at mall Africa a useless attendant mbali hlengwene was the cashier I first asked her to analyze my card n see I can buy n she said yes I have a credit of 1980 after but all my goods amounted to r2219 n then asked her to reverse one item so that it can go bck to r1980 she then advised m n said no ur installment is r143 pay it then ur credit will go up I did as per her instruction then she validated my things and says there is an amount of r138 due that I must pay in cash...I said no reverse one item she says she can’t she has already validated my transaction.she then called her manager and the manager told us if they reveserve all items i will not be able to use account for 24 hours as HR must do an adjustment ,I told them to fix their mess n she later returns and says the adjustment can only reflect after 4 days...if this treatment we should be getting for my money.
