Pathetic service& bad customer service from Nandi

On the 14th December 2015 my husband logged a fault regarding our adsl line. A few days later he contacted the call centre for an update and he was advised it was at the testing centre. Again a few days later he called back and spoke to a supervisor Nandi Iverson who undertook to provide feedback within two days. She never did so. He called back 2 days later and she just apologized for not calling back but still no update provided. She said she will call back on 27 December. Once again no call from Nandi. When he calls her she hangs up. It has been two weeks without our adsl working and when we called the call centre again today we were advised it is with the testing centre. Which is the same update since day one. This is really bad customer service and we are expected to pay for something which we do not have access to for two weeks. Nandi Iverson is a blatant **** and should not be placed in position of a supervisor as she is totally ***********. We expect this fault resolved before close of business tomorrow, 29 Dec 2015 as our fault was logged a long time ago. We also expect an apology from Nandi for the lies and incompetency on her part.
