Bad service Vumatel

My service is up to date....called to have debit order run and what they do is disconnect my line 5 days before the time with no communication at all. Activation says 6 June but what happened to rest of my fibre connection. Till the 6th this is a major inconvenience just not the connection issue but you cannot get through to them via telephone or WhatsApp perthectic pathetic service from Vimatel. I am sitting without a connection for 5 days and I cannot get through to them at all. How evens is this good service. This is not the first time I had issues with them. So what do I do now with regards to work and school work projects, unprofessional is all I can day.
