Poor Customer Service

I was refer by King Price, and the person from King Price said he will ask them to phone me regarding a tracker device, so they phoned ones and I wasn't able to pick the call, then no return calls. So I wrote a mail to the person of King Price again notifying him, Cartrack didn't came back to me. Eventually they did. The person was quick to sold the package to me but no follow-up after that about installation. So I phoned and was refer to one person to another by repeating my situation, then I went on what's app to communicate as well, the same story. Till now after another what's app send, no reply. This is very poor customer service. I've send a message on there what's app group to cancelled my current pending contract, I'm really not interested in continuing with this agreement, till now and it is 3 weeks now and now effort of installing my device. I'm just concern on how long they will react if they can't give proper customer services now if your vehicle get ******. So I lost all interest in this company.
