VUMATEL WORST AFTER SERVICE

I have been with Vumatel less than a month and really there service is the worst I came across in regard to Internet.Yes very quick to do the installation but wait after three weeks there fibre box gave in.I contacted my service provider Mweb and we tried everything.Router all working.Tried this on five devices yet no internet.Contact VUMATEL and gave them the refwrence number.The lady tested came back "sorry sir their system closed thw query as it shows it is working".I explained to her it is not as we did everything we could.I Requested technician to come and assist just to get told "Sorry there is nothing that Vumatel can do as the system close the request therefore will not go through to maintenance/technical.No what no so there is nothing you can do...VUMATEL lady said NO where in your life...I made a fuss eventually she came back and said ok someone will come out to have a look.Listen to this one 5to7 working days.In today day and age and competition really.I rely fully on this internet and this is what being told....no urgency...what kind of service is this.Telkom yes Telkom was FASTER..now I must sit without internet cannot work due to a company that have no after service!This only after three weeks of installation...I will and cannot wotk with a company like this and reading other complaints I am sure they will never pitch up.Will wait one day then I will have to go to every possible social media and highlight not to use VUMATEL.This is unacceptale!!!!Await urgent repsonse....
