Takealot does not understand logic.

On 10 Dec I got an email from Takealot that I got a "Secret Santa Gift R100 off Coupon"(code Epic100). I wanted to order a gascan and got no further with the discount. The next day I saw a La Cocina 25 cm Round 4.7 liters Red cast iron Casserole at R939 and decided to order it and use my Epic100 discount but on the order there was nowhere provision for that. I contacted them by email and got a reply from Suzakele M. how to load my discount voucher...2 options but none worked. I supp**** them with detailed screenshots(without response from them) but because I could not subtract my R100 discount, I did not complete my payment. This morning I got an email stating that they cancelled my order No.***, but that I can re-order it, but now the price went up. I still want the pot at R939-R100=R839. All I want to know in Afrikaans...HOE DE *** DOEN HULLE BESIGHEID??? Then I Googled them to get their helpline phone No. Number is ***. When I dialled the No. the "ghost voice" said: The number you dialled does not exist. It seems to me that they have a standard recipe for business and the moment you deviate from that; a miracle happens...THE PERSONNEL ALL CHANGE INTO *****S. I had a lot of problems when I started ordering from them in the beginning, but somehow it got solved and I ordered an Oukitel power station of R30000, 2 deck chairs, Oukitel phone and a set of cast iron pots without any hassles...UNTIL NOW.!!! Please help, I'm in a flat spin.!!!! It is a big problem when you order stuff on the internet, when you need assistance IT JUST IS NOT THERE. I ordered quite some stuff from Aliexpress and they solved problems without any hassles on their chat channel. Please help.!!! Kobus Bender
