What exactly does your Buy Plan page say about your two upcoming membership plans?
If there are two on your account then, almost certainly, one will start on January 27th and the other will start the following month on February 27th.
Two membership plans can't start on the same date and multiple membership plans stacked on your account should kick in sequentially.
There should be no need for a refund.
