Lost kilometres monthly

I’ve had my tracker installed since last year August, the only reason I had this installed is because of the sars compliant log book: To date I have had to call every month to get my kilometres adjusted as the app or the unit just looses mileage. When you call the call centre they adjust the kilometres to over one million, seriously? Then it’s another call to get that rectified. I have asked Bianca Julius to get a manager to call me as I am not happy with the way things are working, I am still waiting for a call. I am constantly told they will escalate this matter. My concern is how many other people and businesses are potentially losing data that is vital for sars logbooks? Surely I can’t be the only person experiencing this. Poor product, pathetic service and managers hide before an endless all centre that leave you on hold while they try locate a manager! I made another call this morning and updated my mileage, to loose another 3.8km some how and now I am back to my actual mileage and app not in sync again!!! No solutions from this company.
