Frustrating support personnel

It's the evening of the 1st of April 2022 and a debit order has gone through for a service that I could not use since Monday, 28 March 2022. I have been calling them everyday and the support desk has failed to restore my fiber connection. Unfortunately, the WhatsApp line is just as disappointing. You get blue ticked and only get a one-liner response after 30 minutes. This is truly frustrating as I work from home and need the internet to do my work. Would some -one in support do their work and restore my connection.
