After cancelling your contract because I was unhappy with your service.m and Fighting with your agents almost everyday...I thought it would end. I have no effin idea why your useless, *********** people took my money again this month. I fought this fight last month and I received an invoice written FINAL INVOICE with a zero amount...I do not have time for this BS again, just return my money and leave me the F**K ALONE. Yeeerrrrrhhh
