cannot get line fixed since nov2016

<p>our line got possibly cut when they did alteratins in the offices next to us. we have reported the matter more than 7 times. they keep calling us to check the line but it works as the phone is on divert to my cellphone. they then classify the problem as solved....i cannot get anybody to come and check the line. we are paying for services that are not delivered. please can someone attend to my fault and sort it out....</p>
