Technician not phoning me back as promised

Good day<br> <br> I have an issue with my Vox Capped ADSL account.<br> It is not possible to stream any video from Showmax, when I use another ISP Showmax streams perfectly.<br> <br> I submitted a support ticket via email yesterday evening and received no response up till now.<br> I then phoned the contact centre twice, both times the Vox representative informed me that the Senior Technician (Micheal) has been allocated to attend to my issue and they will ask him to contact me ASAP.<br> <br> Ticket number: VOX***<br> <br> 4 hours later and no joy...<br> <br> This is very annoying.
