AmEx Interview process

I have given the 2nd round of interview for Amex which is supposedly last one i guess.. it's been a week now there's no update.. once tried reaching hr through text she didn't respond not picked up the call..

should i take this as no? Is it fair to assume that she saw the text and obviously would have recognised me being the candidate, thus it's implicitly a no?

In a limbo due to this as another discussion is in final stages🤐🤐
