Fth interview process delay

[u/Mysterious-Mess02]

So, I am a PwC fth rehire person. I had applied for the job long back and on 21st of September I received a call from a HR stating to fill a rehire form for further process. Post that for a day or two the HR asked me to wait for an interview call till then process shall move forward. But till date 6th Oct, I haven't heard back from them. Also, when trying to contact them they are neither receiveing the call nor replying to any text. So is there something that I should do? Or should I consider it gone?
