No response as to request for line cancellation

Hi,<br> <br> I submitted an email with all the required documentation for my voice line to be cancelled on 12th of Jan 2016.<br> I hear nothing and again sent an email on 29th of Jan 2016 to request follow up.<br> <br> I have still heard nothing.<br> This lack of feedback is terrible, I want to cancel my voice line ASAP and it would be unfair to continue forcing my to pay line rental if I do not want the line anymore.<br> <br> Please give me feedback as to the status of my cancellation request.<br> <br> Regards<br> Stephan
