Urgent Complaint – Technician-Induced Fault and Unprofessional Conduct

Dear Cartrack Customer Support,

I am writing to formally escalate an issue regarding the recent work performed on my vehicle by one of your technicians by the name Kumaren. After the technician attended to my car, the installed unit stopped functioning since that morning of Tuesday, 13th May. Despite multiple follow-ups since Wednesday, the issue remains unresolved.

I have screenshots of my WhatsApp communication with the technician, which reflect an unprofessional attitude and refusal to accept responsibility. He dismisses my concern, blames network or phone issues (which did not exist prior to his intervention), and ultimately tells me to "do him a favour and escalate it."

I am currently paying for a service that is not being delivered, and I expect urgent corrective action. Kindly:

Send a senior technician to assess and rectify the fault immediately. Investigate the conduct of the technician involved. Confirm that I will not be billed for any fault caused during this installation.

I trust that this matter will receive the seriousness it deserves. I look forward to your prompt response before taking this matter forward. Don't you dare take money from my account until the matter is resolved. This is ******* I am not going to tolerate.
