Keep your benefits and rather give us SERVICE!

My two kids have MegaU accounts and receive "benefits" monthly - e.g. McDonalds vouchers. I have been struggling since March to try and use these vouchers. Firstly the attendands at McDonalds don't know how to use them, so you spend 15 minutes waiting for them to figure it out. Neither of the March vouchers worked. I had to pay for the meals. Upon phoning ABSA, they sent me new vouchers in April, one of which worked and the other AGAIN did not work. I have been trying since then to follow up, only to get told the matter is being investigated or escalated or something similar each time. Now I received an email from someone clearly new to my story, starting in March and asking why the vouchers were never used. What a waste of time, please stop giving us "benefits" that waste our time and rather focus on giving us service, that is the only thing a bank really sells - customer service!!
