Tracking device

My name is Gugu Mswane.I bought a Bmw in 2013 December.A friend recommended Netstar as I needed atracking system in my car.I contacted them and I gave all details and banking details.I was referred to maponya mall to fit the tracker.I followed all their instructions.after a month i noticed that when I check my car on the internet site that I was given,I can't locate my car.I started calling them but everyday I was promised it will be sorted out.I called for more than a month.And each time I get a person on the phone I have to start afresh explaining.I've spent so much money on airtime.I have phone records to proof this.one of the call centre agent was Jarrard,also Orienda.I went to maponya mall and talked to Zipho,who promised to fix the problem.but after few days nothing was done.After two months I went and fitted a tracker with tracker tracker.And I got good service,now my car is safe and the debits in my account are in [URL Removed] later said I'm owing them,but I asked the person who called why they didn't debit on my bank cause I gave them banking details.they said it was their fault their debits were not working.Now they say I owe them 5 000,when it was their faul!
