RCS don't know what they are doing

I paid my RCS account on the 25/07.2021 at 14:32. I actually paid more than suppose to. Last night (6/08/2021 at 22:30) I received an SMS saying "I was suppose to pay my account on the 1st of August. Please make payment bla bla bla". So now on 6/08/2021 at 22:30 you send me an SMS and expect to run after you. Well i can prove you were paid ahead of time. So here is what will happen. You will phone me and apologize for bothering me at 22:30 in the evening and this is after business hours about a system error you financial department have made. I have the prove that my side is correct. Please try and prove your side is correct. You are fast to charge penalties if someone pays late or something. I think you must pay me a penalty for your mistake this time. You have my number. I am waiting for your call..
