I had the most horrible customer service experience in my lifetime

I had the most horrible customer service experience in my lifetime. I manage a contact center as an Ops manager and I was completely appalled by the service. Shouting and screaming over me as a customer - naturally, I matched this energy. I was escalated twice, still no resolution. Took forever to find notes of previous interactions which was clearly aligned to what I was saying. I am so happy I am done with Cartrack. As a retentions Ops manager who has previously provided services to NetStar, I was disgusted in the customer disregard and the disrespect of your employees.
