CarTrack is Harassing me!

I am utterly disappointed in the service received from cartrack , I logged a hello peter complaint on the 25th July, where you responding saying an investigation was launched. Was this investigation to Harass me? As per my previous complaint my account was messed up by you guys now I need to received 4 phone calls a day from your accounts department telling me my account is in arrears, when your agents calls up my account it reflects the account is up to date. Today to my surprise i receive a WhatsApp stating I didn't stick to my payment arrangement, and I was like what payment arrangement... the response I receive is, statement sent to my gmail address , I go an open my gmail address I see a email from Nompumelelo Mphuti.. stating the same thing no payment received. I am feeling harassed by CarTrack, I received 4-5 calls a day where 2 of these calls daily is dropped in my ear when I answer. Go and fix my account and STOP calling and emailing me for an ACCOUNT that is UP TO DATE!!!
