This is not a world class service

I called on Friday afternoon that there was a problem with my adsl they told me a technician would be dispatched on Saturday .on Saturday I called yet again and nothing happened .I called on Monday and requested to speak to a supervisor,I spoke to a supervisor who assured she would get back to me that never happened .on Tuesday I called yet again still the problem has not been fixed .phoned today and.was informed the problem would only be fixed next week Tuesday this is the worst level of service delivery I.have ever experienced in my life .They should not call them a world class provider as this is totally unacceptable they installing fibre optic cables in the wealthy areas but they don't improve their service. I want this fixed today .They said two to 5 working days if they only intend to start working on it next Tuesday that is 10 working days after I have reported the problem .
