I am very annoyed at how Intoxalock gave me the low down with regard to their product because I thought I would not have to pay additional fees. The customer service representative from Intoxalock that I was talking to later got very rude to me and I felt like that was unnecessary. The other thing is that I got an additional charge from them that they told me would be refunded to me. This did not happen at all and I am still waiting for word on the reimbursement. This was very unpleasant to deal with.
