New housing electricity & water connectivity

Hi all. Need some feedback.
I bought new house from Homelite at LiteView4. Was informed that the connection for sesco & laku would take around 4 to 5 weeks.
Are the other housing developers also have the same practice? I have checked wth sesco and laku and they said it wouldnt take tht long. The most is only around 2 weeks plus.
Dunno abt other developers but i thk homelite is getting worst in term of servicing.
