5 DAYS - CANNOT RECEIVE PHONE CALLS

We reported being unable to receive calls on our switchboard on Monday 24/08/2015. They were informed the number *** is not forwarding calls to us. It was explained this is a number which when called, diverts/calls forward the caller to any one of our other numbers (which are not advertised). We have been told repeatedly the problem is solved, then on 26/8 they evidently discovered the cable is damaged. Yesterday we were assured by a supervisor, Johanna, our complaint had been logged as urgent and would be sorted out yesterday. Today is Friday - day 5 of not being able to receive calls from interested clients - this week is the busiest time of the month for us and here we sit, unable to generate no income and our agents, who are commission only earners, have no means of earning a salary this month and we will not be receiving a credit on the services we pay for but have not been able to use for 5 days!!
