Non-existent service from Breedent-Herotel

2 Years ago when I joined Breedenet I was given the option of 2 Mbps for R299 p.m. or 3 Mbps for R399 p.m. I chose option 2 and have been paying R399 p.m. for the past 2 years. Testing the download speed at various times gives me a 1.8 Mbps. My e-mail query met with a response that I am using the service "constantly" via a TV box/Android device. I do not own a TV box and use the service for a total of 5 hours a day. The rest of the time the router is switched off, Tablet switched off, laptop switched off. Asking for an explanation of the "constant" use met with total silence. Referring the matter of the overcharge to the sales dept met with "I don't understand what u need, your e-mail is unreadable". What on earth is going on at Breedenet?

I have now decided to cancel my subscription and go for better options (hopefully), not many ISP seem to care whether they lose customers or not.
