PATHETIC SERVICE FROM Mweb

Hello I would like to post on the pathetic service received from Mweb. I am currently a customer of Mweb, been for many years. My brother that lives with me recently app**** for a new fibre connection to his flat which is on my property. All went well and installer came by to connect up the building however wanted some cash for extra material which he was going to acquire from a colleague. I found this strange and reported the matter to openserve (Installation company) and Mweb service provider, they both agreed that this was not normal practice and said that they will resolve the matter, this was 18 days ago. I have tried emailing Mwebs customer complaints, calling them almost everyday and spent R100s of rands already on airtime explaining my story each time. I can never speak to a person in management because I am always blocked by the telesales consultants who say all they can do is message a manager to call me back, which never happened in 18 days. I find that its pathetic that a company that suppose to provide clients with a means of telecommunications cannot themselves communicate. The next step for me would be to send a letter by post to the Mweb Headoffice and if that fails maybe use a ***eon service.
