Abort the chat facility if you're not competent!!!

I have firstly struggled to have the line active, next I have made an upgrade and for the past two weeks no one has been able to tell me why a 10Mbps line is always running at 3,98-4,21Mbps and with the record upload speed of 0,84Mbps. This is ludicrous and doesn't make sense because I have selected to upgrade my line for running webinars and the speed is unabling me to run my small home business. So far no one has been of assistance when calling or contacting the chat center. You have this lady called Bongiwe that firstly said she will change ports and I didn't see the changes and next David Rakometsi keep online without any suggestions and/or advise to say hold on Sir for a specific amount of time. If this is the kind of service we should expect from chatting to your customer service than abort and stop this chat facility because it makes the organisation look ***********.
