Malas Tyres Unsafe

Please do not buy any tyres from Malas, my brother bought 4 new tyres, not the cheap specials, we went on holiday and the back right tyre just popped due to a defect, we changed the tyre and had that one fixed to use as a spare, the guys that fixed it said it was definately a defect in the tyre, most probably rerhreathed as well. When my brother took it back they refused to xhange it, saying it was his fault as he got a punchure and drove it flat. They are selling defected tyres or retrethed tyres as new. Please tell evey one you know, they can cause death, if that tyre had been in the front we could have had a very bad accident, their ryres are not safe and rhey do not care, the manager is very arrogant and even told my brother that he can go see his lawyer if he wants.
