No support from Dunlop

I bought a brand new Pajero Sport with Dunlop tyres and from the go the vehicle was vibrating. Mitsubishi Centurion did nothing to assist and I went to a local tyre dealer in Centurion who craciously offered to assist. After fitting of 7 more Dunlop tyres and trying to balance them, was the supplier able to get at least 4 that they could balance. The staf informed me they were having many comebacks on Dunlop tyres. They then sent the tyres to Dunlop in Jetpark for evaluation and refund but Dunlop refused. So between Mitsubishi Centurion and Dunlop I have now lost R10K . To all out there careful who you deal with as once you have paid they loose interest once money is in their bank. Check reviews and deal with people who have a clear history.
