MWEB disgusting service

I have been a loyal customer of Mweb for over 12 years. I recently upgraded to a 20mb line and the experience has been disastrous! In attempting to install my fiber they damaged my telkom land line. The supervisor admitted that the man doing the job cut the wrong line. After multiple calls to managers i was told that they can do nothing as they fixed the fiber and its now working and the fact that they broke the landline is not their problem and i should get telkom to fix it. To say that im upset and disgusted in this treatment of a loyal customer is an understatement! it has been 5 weeks and no one cares. Please be aware before making the same mistake. Clearly loyalty counts for nothing with Mweb.
