My sister bought suv from them new, back in November 2019, they said still waiting on a remote start unit, waited all the way till march 2020, said they'll set appt up to install, now they saying unit will be in June or July now?? I don't get it... it's just a remote start? Hope they can resolve this issue, it's been 6 months waiting...
