Worst service

I had Car Track installed on my Vehicle on the 12/2017 through Nissan Hardbody. The debit order was suppose to go out on the 26 of each month but they decided to debt on the 23 and 24. On the 24 of March 2018 the Amount of R199 and then again a debt order of R236.50 went out to cartrack on 02 Mar 2018

I even contacted the accounts Department more than 5 times and explained to them my concern and was asked to forward my bank statement highlighting the 3 debits. Which I did, so they could investigate. its a new month and I am still having issues. this was the last email I receive from cartrack agent "Good Morning Mr T Ma. I am still on your account issue Mr Ma, I am still waiting for response from the other department". Till date I'm still waiting
