water for africa has disappeared

Water for Africa serviced my water filter. THEY harassed me to have my filter serviced-phoning me constantly. I paid them (C F Snyman, FNB WOODLANDS) immediately for their service but on payment complained that the old filters wasn't left in my sink for me to see. In retrospect I can't help wondering if the technician (Johan van Rensburg) did replace my old water filters?? Since the service my water filter unit was constantly leaking and never functioned properly. After numerous calls (0871507947) and emails [Email Removed] I finally got hold of them. After 2 weeks and lots of excuses ( their vehicle and telephone was out of order) they came to do repairs. After the repairs the filter was still leaking, damaging my cupboard and wooden floors. NO answer to my subsequent e-mails or phone calls. Water for Africa has disappeared. No service whatsoever. Waterwise came for service and repairs as soon as I have contacted them. Great service from Waterwise.
