Telkom Refused to replace my new faulty router.

I recently took out an ADSL contract with telkom with a fixed line and the router was delivered on the 10th of July. Since then I realized that internet was slow and I reported the fault. After being told the technician would fix the problem remotely and failing, he eventually came to my house to test and found out that i was getting 5mbs instead of 10mbs. He advised that i take the router back to a Telkom mobile store and have it replaced since it was less than a month. The lady at the store refused sayin it was more than & days so she was booking it in for repairs and i would get it back within 21 days. This is ****************, this is a new router after all and i was not even given a replacement one! I called customer care this evening and they did not know what to do to help. The lady advised me to talk to sales dept. Now, I have several contracts that hinge on me having a reliable internet connection and this is going to cost me dearly. I am appalled at this service.
