Charges for returned equipment second month in a row {removed}

This is the second month in a row you charged $ 4.95 for box I returned 06/15/15 {removed}

On the bill from 06/24-07/24 you charged it And on the new one billing period 07/24-08/23 you charged again. I called and talked to your representative 07/10/15  about it and he assured me it will be taken care of and will not bill again.

I also faxed over returned equpment receipt to fax 847 391 8624.

I need credit for charges 06/16- until 08/23/15 .

Thank you
