Adjustment of Status - I-485

PD 01-03-019.

I applied to expedite my i765 in May 2019. Few days later, I received RFE notification on my i485. But when the mail came in, the RFE was for i130 (online notification not received). My wife(petitioner) responded to the rfe and it was acknowledged online that "response to rfe was received". 3 weeks later, my i765 & i131was approved and combo card was mailed.

My concern is that till this moment my i485 status still remains "on 13th of May we mail you a request for evidence". I have called USCIS several times to clarify if this notification was meant to be for the i130. But I get conflicting information, One said it's a crossover, that the notification was meant to be on the i130 and that there is no pending rfe on the i485. I called a month later, this time the agent said it's impossible to get rfe notice of i130 on i485. I asked him to fax the content of the RFE on i485 to me because I never received it. He said he opened the notification and the content is empty. I don't even know what to do because by now I expect my i485 status to be "ready to be scheduled for interview.

Anybody experienced such? Please kindly share your input. I'm so worried because I'm not sure if I have RFE or not. I don't want them to deny my case for not responding to an Rfe. A tier 2 agent raised an inquiry ticket for it. It's yet to be assigned for over 2 months now. This is really frustrating.
