FNB not responding to premium banking requests

I logged a concern last week on the premium banking on my internet banking and although I received an email stating that I will receive a response in 1 working day I am still waiting for a call. <br> <br> My concern is that I recently bought a Dell Inspiron laptop VIA FNB. Within two-three weeks of owning the laptop the HDMI function has ceased to work. When I plug the laptop into my TV at home it does not connect. WHen I use the same HDMI cable on my 3 year old ACER ultrabook that I also purchased VIA FNB it works fine. <br> <br> I am not willing to pay 10700 in total for a product that is no longer working as expected. Can someone kindly contact me to resolve this issue.
