Shocking non service from a manager

Have been a client for years and have not missed a payment. Currently have two Samsung S23 ultra contracts. Received an sms indicating they want to debit me on the 28th due to the long weekend . I called to ask them to move it to the day after the long weekend as I know I won't have funds for the debit orders. They refused and indicated I will have to make a manual payment. I said I do not accept it as I am inconvenienced by that. Asked to speak to a manager. 22 min total that I have been on hold now. Still waiting. As a company retrenchment your staff and financially struggling against other cell phone providers I would think you would be more enthusiastic to help your existing clients
