Credit Available not eligible to buy what i need

Good Day homechoice, please assist me in this regard, i placed an order on the 20th of august and had to call on the 28th to follow up as it still said "processing order", was told that i had to call to place an order for activation purposes, fine i did that, was assisted, order was re- placed, after an hour i received an sms saying credit criteria not met and the order had now been cancelled, am in 0 arrears, i have more than R4000 credit and the item i needed cost R200, i called to ask why and was told it had to do with Credit Bureau, like i do not understand, i still have buying and the Ts and Cs do not agree with the explanation given. i had to reorder on my own again online and hopefully this time it gets processed, please can this be fixed, rather remove my buying credit than give me false hope because some of the things we order because we need them.
