ONE OF OUR TELKOM LINES IS NOT WORKING 053 331 0006

You just posted to a USA site about a service provide not here.
where are you, locations matter
in fact why not contact them using say a CELL phone
and ask them why your LINES are down.
what ever lines means, (land line? , cable TV, I sure don't know)
call your service provide on a PHONE any phone and ask them, for help. we are not any of that. good luck !
