Metrofibre isp bad service and month long issue resolution

Hi

I'm specifically targeting this to Metrofiber go as an internet service provider. This is the worse service I have received from an internet service provider wrt resolving an issue. I have been sitting without internet for close to a month now. It started when I had an issue, the vumatel which is the network installed a new ont box. The assured me the internet would after a couple of hour but it didn't. I then proceeded to call metrofibre as my isp and they attempted to help me by setting up the router. However this didn't work. So it's been back and forth with them furnishing me with new credentials but nothing works. Even after escalation. They never get back to me. Hardly call me. And send generic support steps on whatapp, sometimes the same credentials. Then days later they escalate. Nothing ever comes of these escalation and don't get sufficient feedback. Either just vumatel did something and then the cycle begins again with credtials and resetting my router a million time over and over. This has gone of for a month now. I'm frustrated and at wits end with this service provider. I'm at the point now of canceling them and getting a new installation from a different provider. They are the worse and I would recommend staying away from.
