Urgente!!!!

Hello, base 4 4. All right, I'm here to ask for your help again, because I asked for it. I couldn't do it in the app. I want to cancel my annual plan for the monthly one. I clicked without meaning to. I only saw when my card bill showed that I was over the limit, and at the time I didn't even realize it was from you. I thought it was a scam, so I blocked the card and now I get this message: I can't go back to the monthly plan. I was born. Because of the high price, I'm used to paying a much lower price than the whole year, so it's like I canceled the card out of the blue. And now I can't get in, I've tried to cancel it in several ways, and I've had no response. Can someone help me with the gratitude answer?
