Router problems

I signed a contract with Telkom for unshaped LTE about one and half weeks ago. The delivered the router - I was very careful to put the sim card in the correct way - to the point of googling it. The sim card disappeared and I could not get the router to work. The sales rep, a lady by the name of Marie-Louise, met with me on Wednesday and we realised that I had been given a micro sim card instead of a normal sim card, therefore the micro sim card had just dropped into the router. She took the router and despite many calls, sms es and emails to her, she has responded only this morning - and I still do not have answers. I have now told her to cancel that router and give me a new one. I am UNABLE to work while this saga is going on. I cannot get hold of anyone at Telkom, because one just cant. I want a sales rep who will bring me a new router, set it up for me and give me service.<br> <br>
