uhm.. what i experienced are totally different..
i personally uses kangaroo
send 20+/- parcel per month.
90% of them arrives on time( next working day)
meanwhile the remain 10% arrive max in 3 working days
.for me i rank it as acceptable ranking.

but for SUREREACH...
waliew
when it was at my ex-company.
however it's the cheapest company i ever seen,
RM5 per first 3kg, rm1 following...
10 delivery, out of 7delivery arrives more than one working day.
And out skirt area taken more than 4 working days...
Call for service also wont entertain one, like tak kisah business..

for me my total blacklist in courier :
SUREREACH
ARK COURIER

Rankings:
NO.1 SKYNET (HOWEVER IT'S GOOD, BUT EXP)
NO.2 KANGAROO
NO3. POSLAJU (HIGHER MISSING RATES, BUT DEPEND)
