Tint doesnt equal lens enhancement???

There's a current winter promotion whereby u get a frame up to R1500 OR free lens enhancements to the value of R1500. So my dad went yesterday on the 04/05/2015 and had an eye test, and chose a frame also. He added tint and was given an invoice reflecting zero balance and told there's no charge. <br> <br> Today he gets called and was told that he needed to pay R1400 as the tint is not covered. No where in the fine print have I read that this deal is excluded from medical scheme packages. <br> <br> Additionally he chose a frame that was 'free' on the Boncap option.<br> <br> So well done SpecSavers for robbing a pensioner!!!
