BAD LTE and Service Response

<p>My fixed line LTE has been giving me issues since Dec last year. 1mbps download speed and even less at some times. I logged the call and after a month i requested feedback. My call ticket had no feedback for me. When I asked the agent how do i escalate the call he told me no they can only make notes on the call but i can ********** After sending them a mail i find out the email address does not exist. This is very frustrating as i previously had a call open from March 2016 to September 2016..</p>
