Hi really sorry about that, trying to do too many things at once and I didn't give all the information that I should have done, so sorry... Anyway here it is...
I was trying to ring Patient Services, Prescription Pricing Authority, Sandyford House.
Little confusing because when you put Prescription Pricing Authority in the search for an alternative number on the main saynoto0870 page it comes up with 0845 6018076 geo of 0191 2325371 and NHS Patient services 0845 6099299
The number I have on the forms for the same Patient Services is different 0845 610 1104 on an HC3 form and 0845 850 1166 on an NC1 form. They are forms for help with claiming health costs for students ect.
I ended up trying the one you have above, geo 0191 2325371 and it works to get through to the numbers I had on my forms aswell if you go through the press number system once connected
So basically 0845 850 1166 and 0845 610 1104 work with geo 0191 2325371
Phew! now you know why I didn't have time earlier
I just hope I haven't confused anyone anymore than I confused myself now
Anyway hope this is useful to someone else
Thanx
