Poor service and delaying refund

I purchased a water storage tank (for R2,585) using the BW online platform on 27 Jan 2018. The estimated delivery date was within 3 weeks. That time was passed and I had to call BW (they put me through to their Constantia branch as the item was suppose to be delivered from there) to get feedback. Well they then told me that they experiencing some problems sourcing the tanks and that it would be delivered that following week. That time also passed without me receiving any feedback. I called again and the same branch told me that it would be delivered that same week and that they will call me on the day. Surprise - that day also passed and I didnt get any feedback. After being disgusted with BW I instructed them to cancel the order and refund my money, and they promised a full refund within two weeks.

Three weeks has since passed and still no feedback or my money back (Note to BW management -- please invest in some talktime so your people and manage clients expectations).
