Faulty Line for 1 year and counting

Good day<br> <br> I moved my business to a new premises on the 1st of July 2014. Internet is very important for me to run my business and we run a VOIP telephone system. <br> <br> I have complained numerous times about my intermittent internet connection. <br> <br> My line cuts off at least 5 times a day for about 2 minutes at a time.<br> <br> Sometimes the connection does not come back and I have to restart my router for it to work again.<br> <br> The router is not the problem as I had it tested.<br> <br> Also it is not my ISP that is at fault, as I have tried various ISP's and I still have the same issue.<br> <br> Please get someone to come and sort it out for me ASAP.<br> <br> Awaiting your urgent response<br> <br> Ishaaq
