ACTIVATION OF SIM CARDS

Someone called me from Selldirect promoting a new data package. I app**** for two lines. Received my two HUAWEI E5573 rooters. I was told to phone and activate my two lines which i did. When doing that i was told one of the simcards was already allocated to somebody else and that i had to do a sim swap at a Telkom store. Went to the Telkom Store and they told my there is only one line activated to my name. Been calling Selldirect from Thursday 28 September to sort this out. Everytime im told that someone will get back to me in an half an hour. Well its now 2 October and still nothing. I cant sit for hours at my word and hold on to a phone that no one answers. Please can someone help me in this case.
