Deletion of old credit card information is not efficient for the users

My credit card was hacked and I received an alert from Simplisafe that my old card was now invalid. In order to add a new credit card it can be done off the app, however to delete old credit card information from an account you need to call a 1-800 number and work with someone to delete the old information.  After working through the chat, which was useless I was referred to the 1-800 number and spent additional time attempting to remove 4 credit cards from my account, 3 of which were the same credit card. As you can't see the card number information it makes it difficult to know which of the 3 that were the same was the correct one. I added the new card and then had to hunt and peck with the person on the call to figure out which one of the now 4 cards was the correct one. We had to delete two, create a new one as the default, then she deleted the remaining cards. What a hassle!! Two issues exist here, 1. you need to reach out to a real person to manage your own credit card accounts, and 2. you must have one default credit card which I understand, but it makes it difficult if none of the cards are valid and you need to start from scratch with a new card and again, reach out to the 1-800 number to have them delete your own credit card info. As I've already worked on other accounts to remove the old credit card and add in the new one due to the hack this is the only vendor who requires this level of effort on my part to remove old credit cards. Expect what should be a 3 minute excercise in your acccount to take 15-20 minutes of your life that you can't get back because SimpliSafe can't write a decent program to remove old credit card numbers. The service is good, but this process was not well thought out.
