After reading several posts about being charged extra or having subscription fees deducted multiple times, I wonder if this happens often to people. Because of this, I’m hesitant to subscribe.
I just wanted to hear people’s opinions and experiences on the matter.
I sub trough the iOS app and haven’t had any issues
A good way to solve some fears you might want to consider using something like Privacy(dotcom). Not trying to shill for them but when it comes to trying something new and wanting to pay for it you can restrict the monthly amount, per cost, per month, per year, per charge and total and you can use 1 time use cards (i dont recommend that here) since you will want to keep paying for it. So for example if you set your monthly spending limit to 22 dollars per month per chatgpt and the system has a bug and they try to double charge you, the card declines. Either way the app and website is free, i highly suggest no to abuse it since its your own money but think of it like a Pre-paid card you can reload and you have full control. I cannot stress enough how many times i use this and forgotten to cancel a trail or a company wants to over charge me something i dint authorized. I hope this helps and if you have any questions let me know 
It seems that the site is limited to a specific resident. Otherwise, it is actually a great idea. I think I might be able to find other alternatives to this. Thank you for the suggestion
By the way, I am only planning to subscribe for one month for now.
