Metrofibre poor service delivery

Metrofibre never does what they promise. Initially took a month to have me connected. When services go down, they also take along time to bring you back online, which for someone working at home a huge issue. 10 months later after activation, they hit me with a bill of R5779. 00 said account was not paid from the beginning..... So here my problem, I signed a debit order, they loaded it incorrectly.. Then canceled the facility. Services where never cut off, so I assumed everything was in order. Tried to chat to a manager, they promised me that one would call back... This never happened. Instead they more concerned about recovering funds than trying to understand the predicament they have placed me in as a client. Calls always get cutoff when you dial them, and then you never get a hold of the same individual, so you have to explain your reason for the call again..... Absalutely terrible company to work with
