WITHOUT INTERNET SINCE 14 DECEMBER 2018

I've never had any complaints regarding Mweb, then i've app**** for LTE and our internet was working fine for two weeks, on the 14th of December 2018 our internet went off, and it's the 3rd of Jan today and our internet is still not working, i've been calling numerous times, been sending messages online with no luck to what the problem might be, i'm so tired of calling and i really think it's unacceptable to be without internet for a service I need to PAY for!!!!!!!!!!!
