I was just told emphatically by customer support that there's simply no possible way Adobe can send me an auto-receipt of my auto-payment. As a small business owner who uses Adobe's services for my business, this is unbelievable. Imagine if I had to remind myself to manually generate proof of payment from every expense I have at the end of each month or even just at the end of the year for tax purposes. I'd have to hire an assistant.
Is Adobe not in the business of TECHNOLOGY? Come on, it's 2020 guys. My small locally-owned trash pick-up service can manage to send me an auto-receipt after my auto-payment.
I find it hard to believe myself. Did you talk to a supervisor in the billing department, or just first-tier support? If the latter, I suggest trying again. If you use the chat agent, type BILLING at the first prompt so you are at least talking to first-tier support in the right department. If they can't help you, tell them you want to speak to a supervisor.
