Complaint Review: Smart Car Tech

We had a client who is running a small taxi business for a popular vacation destination. We hired Smart Car Tech, their demo and presentation was great. Then we gave them our money.First we sign the warning  when they couldn't accept credit card payment because their server was down (and it was down because another one of the previous customer challenged their charges and their account was negative) so they asked us to send a payment via paypal payment transfer methode. After 6 months we recieved 2 android app  that is not customized for us. Two of them design marvels that were approved and yet after another a weeks we still have nothing to look at. They are best in delays, because of the time difference, they are always focused on telling us our project will be updates soon. The only time I have ever received communication is when I deliver any legal action and negative review. I cannot be clearer,I am only saying this about company is that PLEASE DO NOT HIRE THIS COMPANY - they are extremely bad.
