LTE service

I have a LTE router with a telkom simcard. Want to get LTE activated on it as it doesnt pick up at home or in the shop. I know i got LTE coverage at home. They dont even offer to see if i have. he says on the blue simcards it does have LTE activated. Showed him that it only picks up H+ not LTE. I am a IT specialist. Asked him to check on the system to see if I do have LTE on the simcard. Asks for the number and says it does have. Asked him if i can see. Tells me they cant see on the system. Why ask for number? Why would he lie and say it is activated when he cant see on their system? Then he tells me its because im not using a TELKOM device. In my a pinion then it should not pick up telkom network at all. I asked him what is the APN for telkom. He says he doesnt know. Asked him what is the dialing code for internet. Same answer. Another guy says its internet and *99#. I got that in my device setup that way. Even if its not a TELKOM device. Its still a ZTE or HUAWEI. It should pick up LTE. What bad service. should i go to Vodacom rather where they do care atleast about their customers? Can anyone please from telkom assist me on this matter. ***
