Incompotence of Voacom technical staff

I bought Vodacom LTE Bundle, which is a business package. From the beginning I have problems with the package, that is now about 4 to 5 weeks.

There are blocks on the Vodacom card which causes that the router is not usable on a D-Link splitter. I am fighting with these *********** Vodacom people already for about 4 weeks. Do the people from Vodacom know what they are doing???

At home I can not send out email from my notebook, connected with a cable to the router and the same settings as my table top computer, both Linux machines. When i am at work and I connect the router to a D-Link splitter, the computers can even not see each other any more nor can I see my own Linux cloud computer. I get he impression that the technical people from Vodacom don't have any idea what they are doing and are utterly ***********.

Vodacom pls sort out this problem or I think it is even better for all of us to cancel the contract because of incompetence from Vodacom side.
