Embarrasing situation when a new card is blocked due to incompetency!!!!

Picked up my renewal credit card 2weeks ago. Asked the consultant at Mall of Africa if anything had to be done in terms of resetting a pin and she said no. Tried using the card the next day to make a payment at Spar and it said it was declined. When i phoned the call centre i was told the card was not activated and spent about 15minutes on a call trying to get it sorted. Tried using the card again today to pay for mothers day gifts and the card was blocked. Needless to say this was embarassing and i could not make use of the funds on my credit card!!! What the hell is going on Woolworths?!!! Do you not train your staff properly when employing them??
