Bad customer care.

am writing this email with a broken and heavy heart.

I am a reavaya customer and I am not happy about it's customer care.On Saturday I went to Indigilizi to load my cards and the cashier there told me my cards are not working and it makes her machine freeze.I was so surprised because I have been using this cards since January.I had to use taxis to go to work.I was told that I must go to Orlando customer service and tell them my cards are not working.People told me Orlando is no longer operational.Where should I go now?The cards have expiry date and mine expires in December but they are not working.I really don't understand why is that.Can someone make me understand how reavaya operates with their machine.

Something must be done as this frustrates us.Another thing is the one for PENALTY,why don't you atleast upgrade the machines so when you tap it must tell you that you must first tap out before you tap reavaya is ripping us of when it comes to this PENALTY issue,it's day light *******.

I am so frustrated with this issue of cards not working.Please advice accordingly what should I do.
