Metro Fails yet again

I am so disgusted by the service I received from Peter. On the 1st of every month I purchase 10 tokens worth R50 each. I stay on a property with many tenants and would enter a token as needed. Furthermore, towards the end of the month one of my tokens did not want to work. I called the metro prepaid office and Peter told me there’s no ways I can get a reimbur*****t because other tenants bought a token after me and used it. So I basically lost a R50. In a addition metro prepaid policy states that a token is valid for 3years? This is contridicting. Is this how metro prepaid ***** from people?
