My Data contract ended in October 2020, but they continued to bill me, they say i must do a cancellation on an ended contract ? I then explained that the contract has a starting date and a ending date, but they still insist i must do a cancellation, so i tried do do the cancellation but was told i must first settle my outstanding account or else it will continue to escalate, What poor service, Will not see use them again.
