NO ANSWER!!!!!

I run my own business that is dependant on internet for emails and my landline. <br> <br> My landline telephone *** is not working since 16 February 2015. I tried phoning the call centre numerous times but hang up as there is just no one answering my call. I have to call from my cell phone as the landline is not working. The calls cost me a lot of money and I can't hold on forever. <br> <br> Now my wireless internet is saying \limited"so I can't receive emails or use the internet. My cell phone bill is going to be sky high as I need to use it now as a hotspot. <br> <br> I also tried their sms fault services but that was also 16 Feb 2015"
