Good morning 
I became I'll (heart attack) on the 7th feb this year been getting universal credit since 12th feb and also been supplying fit notes since 12th feb was sent uc50 around mid March and had to have it back to them I think was 10th April which I did it was actually sent back the 23rd march 
On my journal somewhere I read if no reply after 8 weeks to contact my work coach which I did
Got a reply from  work coach saying she could see they needed more details and suggested I ring them to see if I could help did this around the 20th may and was told they had got all the information that they had asked on the 12th may 

On the 5th of may rang pip to start claim with them filled in the form and sent back had telephone assessment and had txt from dwp to we should have your claim sorted in 6 weeks that was 10th june
I got a telephone cal about uc50 on 4th june for a telephone assessment on the 11th june on the 10th june they rang to cancel

How much longer will I have to wait for the uc50 to be sorted and when will it be paid from if successful 
As it seems at the moment my pip will be sorted before the uc50
Thanx in advance
