TELKOM - NO SERVICE SERVICE

Since I received delivery of the New Huawei Fiber router, working with a sim card, I have not been able to make or received telephone calls, but my internet is working fine (slow and lots of buffering). I have since receipt of this router, constantly logged errors via my cellphone, staying on the line with each and every agent for sometimes over 40 minutes, testing different cables, diffrent ports on the router to try and get this sorted but still nothing. So U had to take the router to a Telkom shop, stood in line for an hour, was connected via the shop assistant to another telkom agent in a call centre and had to take the sim out place in to my cellphone, make and receive calls, and got told that that would fix the problem........IT DID NOT! I still cannot make or receive calls....so I phoned again, got told to switch telephones (hand sets) did that and still nothing. Then I logged another error, same reason, did all telkom told me to do, cot a new reference number and the call was closed the very same day as "being resolved" Guess what? NOT WORKING!!!! So now I have to phone again...... ***3 - Closed Line still not working ***3 - Closed Line still not working ***8 - Closed Line still not working

What more should I do? Insist on going back to the old copper lines? New router? New service provider???? TELKOM please advise, seeing you are the LEADERS in communication technology???? Or are you the ************? On nr 10210 you claim our business is important to you as provider, why do you not act like it???? I STILL CANNOT MAKE OR RECEIVE CALLS!!!!!! WHAT SHOULD I DO??????
