Vumatel Zero service complete incompentece

The FTTH installation was done more than two weeks ago and the router connected the same day. I have since then spent an hour EVERY single day on the phone to get the router configured, first it was an incorrect address (which I did not provide) which Vumatel could not/ refused to correct. Vuma then configured with the wrong ISP, I had to get that cancelled even though I did not request it. The next issue was an incorrect cell number - a week after installation they suddenly have wrong contact info even though they send me sms's, two more tickets created still no configuration done. Everyday I get promised it will be done in the next couple of hours - VUMATEL is completely useless and the support staff have absolutely no idea what they are doing. This morning I receive an email from Vumatel that they will come do the FTTH installation (that was done weeks ago) again this morning. Does anyone at Vuma know whats going on ?? Another ticket and I get promised it will be done in the next couple of hours, no one can provide an update and the provisioning team cannot be contacted directly or provide any timeline....
