Bad customer service

As a new client to cartrack I am very disappointed in the service i received,i wanted a contract with the company and was advised that the previous owner of my car's contract is still active and they would need to do a forced cancelation,I spoke to the lady by the name of Manaka Tloubatla who advised that i send her my natis document together with my ID copy in order to start the process I did that on Thursday 30th Jan 2024,I never received an email acknowledging receipt of the documents and no feedback received. I had to call and do a follow up myself for the past 3 days and everyday I am getting promises that Manaka will get back to me as she is either on another call or on lunch ,till today i have never received a call or an email from her.
