Failed line Support Call not attended to.

<p>Since the maintenance was done over 8 weeks ago my fibre line has been unusable.</p> <p>I have been charged twice since for premium data I am not recieving.</p> <p>I have reported to support and been sent through leaps and hoops but never get a response afterwards.</p> <p>How can I escalate this issue? the support system does not work, It does not allow me to attach the speed tests requested and replying to the operators email fails too.</p> <p> </p>
