Shocking *********** service

I was offered a R 600 Isabella Garcia voucher by Platinum Life due to my partnership with them. I used the voucher on the Isabella Garcia website and the website offered a discounted perfume if I pay in R 99. I placed the order and paid R 99. I received an e-mail from Amekulani from Isabella Garcia, stating that the discounted offer is not valid for vouchers. This is mis- representation on the online store. Then I received an e-mail offering me a R 200 on top of the R99 I paid. Soon after I received a phone call from Amekulani stating that I cannot use the R 200 voucher, as she made a mistake issuing the voucher. I have to use the R 99 in the online store. The only product they can supply at that price are samples @ R 25 per sample. No refunds under R 100 is done. I am no longer interested in this company or any products. i have requested her to cancel the order and collect the original order. No response. I phoned their offices on 9 February asking to speak to a manager or director. I was told that they cannot transfer calls to management. My number was taken for a call back. To no surprise, nobody has phoned. This is the worst company to deal with.
