I guess nothing is for free. It all started when we submitted our booking forms for the 2 night protea stay on the 08 Jan 2016. We waited 2 weeks, no response, phoned call centre was told an answer was forth coming in 2 days, 2 weeks nothing, phoned again was told in another day. Finally received confirmation on 28th jan, booking is confirmed (check in:12 feb, check out 14 feb), voucher will be couriered. Waited a week, since then have to phone call centre everyday, promises voucher is being couriered, there will be called back with a tracking no. that never happens. We contacted the hotel they advised we require the voucher otherwise we have to pay for the booking. We basically planned our weekend, booking events and taking leave and one day to go and we have no voucher. Each call to the call centre is 30 to 45min on hold and when you get through there cannot care what you are saying. Samsung your great deed for your customers, is unfortunately only going to bring great pain to your company.
