Billing for expired contract

<p>My contract expired. Last month I was billed for the data, since my contract was not cancelled. Now I went to cancel my contract and I'm being billed for the device which has been paid off and the data I did not receive. I logged a case on the 6th and was told to wait for 72 working hours which have now passed and still have not received a call from you guys. I called 3 times this week and I kept being told that agents are putting comments on my case number, like what the f#ck? Comments and comments but no fu#ken service. No one has attended to my case and when I called today, I'm told about the same comment nonsense on my case. Can you just fu#ken solve case ********** 7. </p>
