Bilt Rewards review: Lack of direct contact with bilt team. There is no customer support

My statement for my master card for the period of

8/21 to 09/19 reflects two charges for my monthly rent. One dated aug. 21 and one dated sept. 18.

In the past, charges appeared on my statement dated when my lease company receives and cashes my rental checks, usually by month end.

Your instructions are to mail my rental checks on the 21st of each month, so the checks would be received by the month's end.
So why does the september rent payment charge on the 18th appear on my current statement, which is reportedly the billing cycle to 09/19/25 ?
