Worst Response time in solving a coupon issue ever

Me and my wife each got R200 coupons for Takealot. She used her coupon and upon wanting to use the second one she was told by website she can only use one. Well then I tried to use my coupon and buy a game for my son with my card and details. I then got some weird error meaning coupon does not want to work. We phoned Takealot customer support where you hold on forever 8 to 15 minutes or longer. The support consultant we Ziyanda Nombulo who picked up said she could not help us as she cannot resolve and must escalate further. I emailed her thew 2 coupon numbers. She emailed back after 3 days and said well the one coupon has been used she now has to ask them to check the 2nd coupon which should have been done in the first place. The first time when I phoned was on 30 Nov 2015 and the coupon expired on that day. She guaranteed me that they will issue me a new coupon as or if the fault is on their side.It is 8 Dec 2015 today problem not solved, no responses on my emails anymore.I have used an immense amount of my time writing 8 or more emails and making phone calls from my cellphone to them and holding on forever. I have basically spend more than the R200 and the games now out of stock.
