EWA English Refused My 14-Day Refund Request

I purchased a Premium membership for the EWA English app through Google Play. I specifically noticed that the package description stated that it came with a 14-day money-back guarantee. Based on this information, I made the purchase trusting that if I was not satisfied with the service, I could cancel within this period and receive a refund.

Because I was not satisfied with the product, I requested that my membership be canceled and my payment refunded shortly after the purchase, on September 15, the following day. However, my refund request was rejected by both EWA English and Google Play, and I have not received any refund. This has been extremely disappointing because it appears to contradict the 14-day refund guarantee advertised by the app.

I request that the 14-day money-back guarantee stated by EWA English be honored, that the Premium membership fee be refunded to me through Google Play as soon as possible, and that my subscription be canceled.
