Poor service and service delivery

I bought my car from GWM Boksburg on 25 October 2018 My tracking unit was installed and all was fine, however on 13 November I received a call from an account manager who had informed me that the unit was not active and they had to recheck... Which was fine... Then I had to complete the tracking contract with debit order details to keep my account active, however a month later and nothing..... When calling today 19 December, not one of the call center agents have put me through to the account manager and rather drops the phone in my ear, 7 times later... When I eventually get a call, a lady tells me that the lady working with my account is not in today and that NO ONE else can assist me... What is that..... Then when I ask for feedback she talks over me and ignores my requests for feedback and a call from the account manager.... I cannot believe that this is the service we receive from this company,,,, imagine the service you will receive when you are really in a crisis situation... It's terrible....
