Reactivated my old account, and double charged me.

After successfully cancelling my service in March, and not being billed in April, I check my statement and Axxess took off my previous ADSL fee for May. I go to write a complaint, and after I send it off I check my DSL status through their site and I see that my account is still \disabled"but reactivated...<br> <br> I sent them this information"
