Double-bill breakdown

Noticed a double-debit on my bank statement from MiWay and I was confused. Went online and had a portal Chat with Rose. Apparently there was pro-rata which had to be paid because I had changed my debit date. I didn't understand why so many debits were running from MiWay, but rose gave me a break down of what happened and ran me through the billing and all was clear. Still waiting for feedback from her with recommendations from her investigation she initiated.
