NOT being able to speak to someone's Boss

We have asked to have Fibre installed at our home through MWEB the advice and assistance has been terrible from MWEB in that they never know what Telkom is doing and keep blaming Telkom when surprisinglt to date Telkom have been easier and more efficient to deal with than MWEB and when one wants to complain about the service you are receiving you are unable to get past the person you are dealing with as I have called twice now to get Megan's Manager or Director on the phone and all I get is Megan asking why I am complaining about her - how does that work and where is the Client Service in that and she keeps saying \YOU need to Understand"how about MWEB do what they promise and what they are infact charging the client for instead of expecting the client to UNDERSTAND!"""
