Vodacom wheels are falling off! Management to be blamed!

i have signed a contract for uncap fiber on 13 Feb 2019, two months later I must find out myself that Vomatel does not do fiber in that area for business. I told Vadacom they said i must take a LTE 100 gig for R599 until the fiber is sorted. Three months later just cut off my LTE, bill me for installation on fiber (NOT INSTALLED) and the monthly fee. Now I must run the business with out internet. after lots of calls my LTE is on and R900 is the new bill for 100 gig (new router again). I have phoned and ask for management only, everytime they said they will phone me back, not ones they did!. My new bill is Fiber plus LTE I only have LTE
