They shipped be a remote start with a immobilizer ...

They shipped be a remote start with a immobilizer that were not compatible. At the end of the professional install my pro tried to plug them together and NOT COMPATIBLE, he also told me they unnecessarily sold me the most expensive immobilizer instead of a cheaper one that does the same. Called the company, they said the sales guy should have known that and we can take the part out ship to them and they will ship the right one. Since they ordered the wrong part I wound up paying for 7 hrs worth of install instead of 1.5hrs. After buying $140 worth of parts they said they would give me a $10 credit after it cost me $150 more than I expected in Install. Then they offered me a $20 in store credit. What a slap in the face. They said they are sorry they can't do any better than that. Even spoke to a Supervisor, then manager. ALL said the same. VERY POOR Service from a VERY BAD COMPANY. I will NEVER do business with them again and recommend anyone not to.
