No response/update on service tickets logged over a month ago.

Phone line at home has been giving problems with crackling on the line, poor sound quality on voice calls and slow/intermittent ADSL service. No interaction or progress on tickets logged online 2 January 2018 (Tickets: ********** 1 and ********** 1). Now line is completely dead, no dialtone. Additional tickets logged 18 February 2018 ,(Tickets: ********** 4, ********** 9 and ********** 7). Over a month on the original tickets, which if resolved would have probably avoided the totally dead line.
