DISHONEST, NO SERVICE

I hade 4 MX3 contracts with Matrix for a few years. As long as I never expected anything and never contacted them all was fine. In January one of my vehicles was totaled and I canceled the MX3 subscription for that vehicle. It is now July and I am still invoiced for all 4 MX3's, the only thing that changed was that the vehicle I canceled are low listed as Cash rather than rental and the premium has actually went up for this one unit from R233 to R252. I have send several emails and got reference numbers for it, I have also spent more that 2 hrs on phone calls to try and resolve the problem. No one from Matrix ever reply to an email or phone call they owe me more than R2,000 for over invoicing and it still increase every month.
