Horrible customer service

No stable internet connection the whole of March, the consultants keep sending me from pillar to post both on WhatsApp and via email. They are always waiting for Vumatel to get feedback, they ask for pictures of the router and hardware every day and I send that to them but it’s the same thing, no one is even bothered. Customer service is really horrible and I’ve actually recommended this business to close friends not knowing that it’s not great! I have a whole thread on email and WhatsApp and nothing is ever resolved! Been issued countless tickets and they have all been closed without any positive feedback.
