unhappy customer

Money was debited from my account on the 25th like it usually does but this month they cut off my wifi and say i didn't pay. When i call in i was told to provide my proof of payment which i did. But nothing is being resolved instead am being send from pillar to post. Today its day two of not having any connection and my case not being resolved. I have been a loyal customer for the past three years but i will have to reconsider moving to other networks. I mean the game is gonna be on and i guess we wont be watching
