TWO MONTHS AND LINES HAVE BEEN DEAD

we have been experiencing landlines problems for over 2 months now... ive log calls regarding this problem ive had them come out but nothing happens there aftre.... now i find out that the cables have been damaged by the muncipal workers than when i call telkom this morning they mention to me that no the busy replacing the copper cables with some other cables... who do i believe??? and guess what the best part is that each month they still billing me and expecting me to pay... im seriously thinking of finding a new service provider as telkoms service has reached the limits for me..
