first of all im not ranting, complaining or attacking anyone or any sort of occupation or look down on ppl .

im going to renovate my house and engage with several contractors to compare price and what they can do to renovate my house.

these contractors , 4 different contractors, they seem don't bother much about the my renovations. Means they are not responsive. few of them came to my house and measure and discuss, then after 1 month, still haven't give me the quotation. another one not replying my message. sent few messages , no reply and even voice message. when i call them, they just reply me everytime, "next week, next week" then no reply after that even few weeks ady past.
May i know is it my problems that im expecting  whatsapp reply from contractors? or all of them only looking for few millions ringgit renovations and dont bother few hundred thousands reno? if few hundred thousands reno they dont wanna do at least reply me "we can't do it for you or you go fly kite" .At least a reply right? . but now just no reply?. weird

i dont expect a good customer service or immediate reply as they are not from service line, they are contractors. but no reply at all. I also know daytime they will be at the site. but i usually message them at night .

kindly share your experience renovating house and i wanna know is it normal for my case.
