UNFAIR CHARGES

AXXESS HAS BEEN GOOOD , I CANNT REALLY COMPLAIN MUCH BUT WHAT MAKES ME ANGRY IS THAT , IF I AM UNABLE TO PAY FOR MY WIFI BECAUSE THE FINANCES ARE TIGHT , THEY TERMINATE THEIR SERVICES WHICH IS NOT A PROBLEM TO ME , BUT WHAT I DO NOT UNDERSTAND IS THAT WHEN I PAY THE FOLLOWING MONTH THEY TAKE THAT MONEY AND SAY IT IS FOR THE PREVIOUS MONTH( WHICH I DID NOT USE BECAUSE THEY HAD TERMINATED THEIR SERVICES) THEN CONTINUE TO ASK FOR ANOTHER PAYMENT . LIKE WHY SHOULD I PAY FOR THE WIFI I DID NOT USE???
