complaint on maynilad water

have checked he website of maynilad and among other things i was looking for their contact number to complain against their billing and accordingly, the number to call was 1626 and this number is 24/7 contact center..but when dialled, this number is not in service and sinayan lang ang time ko sa pagdial ng number na yun.  i tried doing it several times to no avail.  it was of no help t all.  

i emailed my complaint @customer service of maynilad and waiting for reply.

service seems to be poor, but left with no choice as they are the only ones providing water to bf homes.

sorry ka na lang dahil wala kang choice.
