Still no service delivery!

We still have an ongoing NO service delivery happening. I log ticket after ticket and even get advised by sms that our issue has been resolved....but actually nothing has happened. I speak to the call centre and they just tell you that it is out of their hands...but all they have to do is send a technician. Every call centre agent gives you a different story....some don't even log your call - as you phone back and refer to the call and get told that a ticket was in fact not lodged, but they will do one now for you? I don't think there is an internal communication system at Vumatel? I get some raving reviews from friends...the reason I decided on them in the first place....but now....can I recommend them?
