debit order on a wrong date.

I would like to express myself about the service I recently recieved from Miway. I joined them 3 month ago but I am already not impressed. Last month they ran a debit order on a wrong. Infact they deducted earlier than our agreed date. I gave them a call and we sorted it out. As in like today the debited earlier than the date we agreed upon. I am not so impressed with this.
