pip fiasco!

hi to everyone,iwas wondering if anybody can help me .
it has just been over 1 year since i made my claim for pip,told in dec 2013 i was to go for a medical,this was confirmed by the spanish authorities feb 2014,had medical march 2014.......well since then the pip office have not recieved the medical back from spain today i got a phone call from local medical authorities to go for another medical next week!!!!
this is where i need some help...can anyone tell me a phone number to call for pip which is not the usual front desk person who gives me the usual load of nothing,am fed up of the situation ,i want to talk to a case manager or someone with more information.
right at the begining i sent a copy of my last medical taken march 2013 this was ignored as it was 3-4 months too old to take into consideration!well it is now 4 months on and this medical is out of date aswell in fact if it takes 3 months for any of my medicals to get back to uk then they will all be out of date to be used.
so a new phone number or email to get proper information.
thaks

hi gordon,took note of your message earlier this afternoon,am afraid both websites you gave give out the same number i have used all the time off the pip office paper.also you can i ask for case manager (not neccessary the one who has dealt with you before!) to phone you but it is within 5 working days!!! not 3 hours.
would you happen to know if there is a time limit on getting an application done?
reason being i reckon if things carry on the way it is just now for my application then it might get confirmed by xmas 2014! having today been asked to go for another medical (not asked by pip)the time it will get sent back to uk and translated will be 3 months just like my other 2 by that time it will be out of date just like my very first medical i sent in as evidence at the start of my application which they told me was out of date (3 months!)
is there any mps i can write to etc? would it be worth while?
regards

hi gordon,here is a quick up date on the fiasco....
after phoning the pip office in uk requesting an urgent phone back due to information i wanted to get confirmed and the fact the person at the other end would not know anyway!
i have been trying to get confirmation from pip if the correct paper work for my medical should be the e121 form or the same pip papers which are used in the uk.
so far after 5 days no one has phoned as they said they would (now the 2nd time this has happened)tomorrow morning i have another medical which has been requested by a phone call only from the spanish authorities,i would of thought a letter or phone call from the pip office in uk was supposed to be sent ..?
with no confirmation from the uk i forsee this medical going the same way as my previous in march 2014,groundhog day scenario.the pip has no plan of action or back up plan in dealing with medicals abroad (well spain )they wait for things to come .rather go and find out why it has taken so long or where is the medical!i was informed end of may come june that as my last medical was done in march they wait 90 days/3months before doing anything about it!
hands down tomorrow will be the same
