hi I had the same issue of inconsistency I received a phone call last week and was told in detail what my award was for both living and mobility payments and how much I was owed,I called 6 days later to ask when I should expect it as I was told within 5 days I will receive my back pay only to be told that the system says I haven’t been awarded and the letter posted said I haven’t been awarded I suffer with severe bpd(borderline personality disorder) so this caused me to have a major episode I called back 10 mins later to be told there’s inconveniences on the system and they would investigate it, within the next hour I received a call from the same person who called last week and told me I had been awarded she called to assure me I had been awarded and the system had a “hissy fit” and didn’t put my claim through I now have to wait another 5 days due to “inconsistencies” the same issue happened when I applied the system didn’t put my claim through for assessment I called 3 months later to be told nothing had been done with it this seems to be a very common thing with pip systems
