Transportation damage to cars

we shipped 2 cars down to their depot in Parrow in the Cape . dropped the off in Boksburg/.Gauteng on the 3rd May and collected from Parrow on the Monday 9th May . We were asked to inspect the cars for damage and did so ( cars were very dirty ). drove them up to Sunningdale /. Table View /. about 30mins drive . The following day cleaned both cars and noticed my wife's MX5 was damaged of one of the wheels ( one of the spokes on one of the wheels had a bad mark and in my opinion it was apparent that a hold down strap had been chaffing the mag wheel on the spoke ). A broad mark about 35mm wide on the edge of the spoke and on the inside of the spoke had been caused by something rubbing and had gone thru the paint on the spoke . This was the driver side front wheel. After phoning my contact at Boksburg , Tanash, it seems quite clear he was not going to assist me as we didi not report it at the time of collection . My 2nd call this morning confirmed this . To reiterate , it must be the hold down strap they used on the vehicle when they transported it to the Cape . I do have a photo of the damage and it was sent to Tanash . I'm not getting anywhere with this company and would not recommend using them to move CARS
