Consumer nightmare

Requested for a settlement letter for my Sanlam and Woolworths accounts of which I did received same day on the 19th of Jan 2018,BUT the settlement balances on both were so incorrect I nearly fell of my chair.. never the less the Woolworths one I could live with, what is a few rands between "friends" now, so I settled that one on the 22 Jan 2018 and requested a letter confirming that I don't owe Woolworths anything any more well I'm still waiting 2 weeks and waiting waiting no response to my emails nothing , BUT the Sanlam settlement nearly equal the starting balance quoted in 2015 so I've requested a new settlement letter for Sanlam and jip still waiting send this on the 29 Jan 2018. They just ignore me like a stop street....they don't care and I think this attitude filter from top management to their juniors ,there is just absolutely no urgency with this people or maybe is it computers....which are offline FOREVER maybe?
