Poor service traker check.

Called Netstar to test the device in my car today which i check once in a while and they said they can't pick it up or my registration. They then told me to call back on Monday. Today is Saturday. So between today and Monday what happens? I don't tell them not to deduct their service fee on time! Disgusting service!The consultant also said she will send me the contact number to call via sms. No sms received! No reference number for the call either.
