Customer service agents keep hanging up the calls, the device stop working and I had to pay for a wrecking service to take the vehicle from my job to the service center, I was told I was getting a new device shipped and I will get refunded for the reinstallation and recalibration, the device took four days to be shipped, was informed by a ride representative I was getting a credit for the whole month, and after the device was reinstalled withing the hour I got a lock out. I had to called three times to get someone because the agents keep hanging up, when I got someone they explain they will notate to get a credit for the lockout, I was not able to talk to a supervisor according to agents they are not authorized to contact a supervisor. It's been 11 days that I have been feeling with this company and their agents to get the reimbursement, they keep asking for the same invoices that I have send for a whole week. And they can't find the invoices I send them at [protected]@intoxolock.com. And while i'm still waiting to get refund of $290. And keep getting excuses. Now I was charge again for the payment and the credit is non existent. This company really sucks. I give kudos to the spanish representative they are more helpful but still with no resolution.
