HORRIBLE ********** HEROTEL

I recently changed jobs and informed Herotel on the 9th of January that I'd like to change my debit order date to the last day of each month. The consultant let me know that it was too late for January, however, an EFT payment would be ok and that Herotel had set up my amended debit order date successfully for February. This was after I had filled in a form to confirm the change. TWENTY days later, I received threatening emails of account suspension and that they couldn't track the correspondence from the 9th of January. So, first of all, Herotel's incompetence is now leading to possible account suspension added to their unwillingness to change the debit order date to the last day of the month. CAN THIS ACTUALLY BE HAPPENING? Can companies really be this ***********? If they suspend our account, we are done. I work from home and can't afford to not have wi-fi. Apology incoming??? I certainly hope so ....
