Hi! I understand that your MuscleFit subscription is cancelled, but you're still being billed. Let's work through this together so you can stop those charges.

First, can you confirm:
- Did you cancel the subscription inside the MuscleFit app or through Apple’s subscription management on your Mac?
- Have you received any email confirmation of your cancellation?
- Are the charges coming from MuscleFit on your credit card statement or listed somewhere else?

Generally, here’s what I recommend to stop further billing:

1. Verify subscription cancellation in your Apple ID settings
- On your Mac running OS X 10.15.7, open the App Store app.
- In the menu bar, click on your Apple ID (your name at the bottom left).
- Select "View Information" and then go to "Manage" next to Subscriptions.
- Find "MuscleFit" in your list. If it shows as active, try to cancel it here again. Sometimes cancellation through the app does not sync correctly with Apple’s system.

2. Check your MuscleFit account online
- Go to MuscleFit’s official website and log in to your account there.
- Navigate to "Subscription" or "Billing" settings. Confirm the subscription is cancelled and you are not active in any recurring plan.

3. Contact MuscleFit customer support
- If both Apple and MuscleFit show your subscription as cancelled, but you’re still charged, you might want to reach their customer service for a refund or manual cancellation.

4. Dispute charges with your bank or card issuer
- If MuscleFit charges continue despite cancellation, your bank can stop future payments and help investigate unauthorized charges based on your cancellation proof.

If you need, I can guide you step-by-step through managing your Apple subscriptions on your Mac or help find MuscleFit support contact info. Would you like to start with checking Apple subscriptions?

Are you satisfied with this plan so far?
