Regarding Delayed Payment Processing

Regarding the delay in payment processing fro apple credit card. As a customer, I have always made timely payments for the services I have availed of. However, I have noticed that your payment processing takes an unusually long time, often taking up to 10 days to complete. I need clarification on this delay, mainly when most credit card companies process payments within a day or two. I have experienced several issues with payment processing, especially when using my bank account. It takes an unusually long time, often taking up to 10 days or more to complete. I have not been able to utilize my credit card for the entire month of February, even though I paid it off. I paid $5,300 via cashier check, which took ten days to process and seven more days to post into my account. It is hard to believe that a credit payment can take 10+ days to process, primarily when most credit card companies reflect their payments the next day. This delay has perplexed me, as I am unsure why processing my payments is taking so long. I understand there may be some processing time involved, but I believe 10+ days is excessive and unreasonable. I have tried to contact support, but either they send me to the auto bot, the support tech doesn't explain why this is happening, or they have no idea.
