Netstar has the worst customer service

A week ago i sent them a mail - got no reply. Then I tried to phone ....the agent was not very helpful and was laughing the whole time ...she started telling me that the driver of my car is Simpiwe and at 5 she started with hello hello hello and ended the call ...the second time i called the call just dropped ... The 3 time i waiting for a very long time for someone to answer ...i started telling the person that i just wanted to confirm the driver and then do an upgrade on one vehicle ...just to be told that she will have to arrange a call back as they experience high call volumes... i could not accept tha and asked that we continue ...so the old trick of netstar came out ...she started hello hello hello and then the call ended ....if this is how netstar is treating a household with 3 vehicles.... then i really do not know what will happen of i need them ...i received the worst service from this company and will NEVER use them again and will not recommend them - STAY AWAY FROM THEM.
