Bad Service

As i experienced bad Internet service last week 17/02/2015 i called the Amobia Customer Service to help with the situation of slow Internet speed.. I have a 2MB line but i only get 0.5MB of speed when i test my network. After numerous calls where as i had to follow up with Amobia where no one called me back they made changes to the line and totally disconnected it for some reason till Saturday where it came back on but since then it has been handled by numerous technicians but still no one has come back to me about my slow Internet connection.. As i have called every time since this matter has been reported i THINK that as a client of such a company they could at least handled things in a better way... As from 23/02/2015 19h04 Amobia is still looking for a problem and i have no answers as to what is wrong of what can be done.....
