SHOCKING SUPERSONIC DURBAN

I wrote a review two weeks ago regarding the shocking service I receive from Supersonic Durban Umhlanga. The came to try and fix my phone but could not rectify the issue and said they would come back the next day or following Monday. They have yet to return or respond to my what's up. I am at my wits ends as I paid a fortune to them to install the phones and fiber lines and have had countless line interruptions and no one able to resolve the issues. CAN SOMEONE PLEASE GET BACK TO ME!!!!!!!!!!!!!! SHOCKING SHOCKING SERVICE SUPERSONIC
