When to look for a warehouse?

My view: book load, 1p1d, 5 entities involved (brokerage, me the carrier, shipper, receiver, manufacturer), p/u great, del next day informed by rcvr broker didn't schedule correct so appt canceled, broker "thank you for your patience while we secure a new appt".

Next day same story but now broker is radio silent through email. (24 hours)

This am (36hrs) I email ~"do you have pref for a warehouse or do you prefer return to shipper?"

Silence.

Now (48hrs) contact shipper for return but they can't take it, lady was nice enough to smuggle me into the ongoing email chain. According to the chain next del appt avail at rcvr is in 2 weeks which explains the radio silence haha.

Zero progress made in resolving this in terms of info in the email chain. Brokerage has always paid layover so thats not the primary concern. However, unlimited layover is not a service I offer so what is the most professional route I can take and when?

On a human to human level I'm super cool being flexible because a lot of people in this industry have helped me when I've had a rough day. So that's my baseline approach regarding this but there has to be a line in the sand somewhere.

Thoughts and advice please.
