Mweb fibre non service

Hi , I have been assisting my sister in arranging for the provision of a fibre internet service and decided to go with Mweb. Her line was originally with Mconnect who for unknown reasons just closed shop. The service went live on the 23 of October and suddenly stopped working on the 29 of October. My mission to try resolve the issue began the following day. I have literally spent hours either holding on their automated answering service and speaking to numerous staff who don't resolve the problem and who also promise to get back to me and never do. I have been transferred from technical to sales departments and vice versa. The calls are not picked up or you wait a ridiculously long time before they do. The problem is of a technical nature as my new WiFi modem needs to be connected to an Ont device as opposed to my previous modem which acted as a modem and a WiFi device. I discovered today from the Mweb sales agent that Vumatel who are providing the service on behalf of Mweb do not have Ont devices and are waiting for a shipment to come in! The gentleman I spoke to at Mweb sales promised to get back to me today with a solution but needless to say I am still waiting. Over and above this I have left three messages on the online query faculty and still nobody has had the curtosy to get back to me. I stated that I would report the issue to Hellopeter but even that did not prompt a response from them Highly disapointed and frustrated by the absolute lack of service and the fact that it seems no one takes responsibility for this. Shame Mweb! The account with Mweb is ***8.
