Auto-compensation - preempting issues

Hi guys,
 
My Virgin service is finally due to go live this Thursday, thankfully. 
 
In the run up to it I have put together what I think the compensation and final bill 'credit' should be. Putting this here as I know it can take a couple days for VM staff to see the posts.

I have 102 days from install go live date (in home appointment), which they didn't turn up to do my inhome appointment, it later got postponed (it was postponed after I got in touch to ask where they were, it had gone past the 1pm end slot, I never got any message to say it, it was me prompting them to tell me what's happened). 

The second appointment also got missed. This time I got a message to say it was missed and will get the missed appointment compensation, which is never got for the first. 

I also have the £80 joining credit. 
 
I work it out as my total amount of credit, including the joining credit as £778.86. 
 
Am i actually eligible for this? I know the terms are muddied in the water to try make it difficult to claim.

Workings are as below:
