Agree with Loony, if it you are struggling at any stage to the point you are distressed like the OP how on earth can this be assessed over the phone!
OP was truthful enough in describing where she was at, and got even more frustrated. Things can change rapidly, at the point a woman feels she needs extra support whether that be pain relief or reassurance she deserves to feel confident in the knowledge that she will be listened to and assisted.
Midwives spend our whole pregnancy telling us that every pregnancy is different, and yet we are all supposed to follow a set pattern for labour?
I have been told twice that 'nothing was happening' and encouraged to go home, if I had not have stood my ground I would have given birth in the car or hospital car park!
With DS2 Pain relief was not offered, and I was made to feel like I was being a wimp, until my waters broke and I was about to deliver my son, cue lots of panicking and trying to move me from a side assessment room into delivery while calling for assistance!
Had I have been listened to I would not have had the experience that I had, hence planned home birth for DC3, which was great. Same planned for DC4 due in 5 weeks.
I hope the OP got to hospital and was treated sympathetically and not fobbed off and is snuggling her baby as we speak! 
And if she had to expand the truth to get someone to listen then surely all that matters is a positive birth experience and safe arrival without unnecessary stress on the OP's part.
