Review I am highly disappointed

Bought sofa a few years back and they were scratched, filed for exchange and we were ignored for the entire year so afer 3 months we stopped paying. They came with display sofas to exchange and we refused them more months passed then finally after almost 2 years they exchanged them (seeing that we refused to pay for crap and wanted them to take them back, infact we didn't want to continue any more and they begged us to bare with them and that they will fix everything including the payment arrangements and defaults and so we made new payment arrangements,whereby we would only pay for the interest for certain unumber of months then commence back to the original installment) now we've started paying the installment of R1500 and have done so now for over 6 months and are suddenly handed over to the collectors as the store kept the interest piling without our knowledge as we are not even getting a statement sent; even though they knew what we have been complaining about and knew about the arrangentments and are forcing us to pay interest of over R15 000 now. I am really disappointed at how they treat humans.
