Prescriptive about when in a year optical benefit can be used

I am on the traditional plan on Bankmed Medical Scheme, paying close to R6000 per month for a dependent and I. Despite this they refuse to bring my optical benefit forward by 3 months as their Optical benefit only refreshes every 24 months, it makes no logical sense that you are prescriptive of which month in a year the benefit refreshes i.e I last claimed for spectacles on the 8th April 2017, and I am told that I am only able to get new spectacles from the 9th April 2019. This is just ridiculous, even after sending a motivational email explaining that my sight has deteriorated quite substantially over past two years my claim is rejected thus took over 7 days by the way with follows twice a day to Opticlear. I am asking for 3 months grace period since you are so prescriptive on when a consumer that pays exorbitant amounts of money into your scheme as to when in a year benefit can be used, every other medical aid has benefit that renews at the beginning of every year and it is also recommended that eye test are covered annually however with Traditional its only covered every two years. Where is the people element of your scheme bankmed is it all about making money? Please could I have someone assistance to have this resolved, if you give me the 3 months grace, I am not going to have benefits until they are refreshed in another 24 months. Look forward to your feedback
