Request from Personal Use Verification form - response times?

I understand from reading through some of the forum posts that a typical response time to submitting the PUV is in the order of 30 days...has this now changed? 

I submitted my initial claim - and TV acknowledgement (4136346) - on 11th June: I sent two email follow-up / chasers to check progress, etc. - and as of 30th July....nothing: no email response, no TV access, nil - my TV13 still times out with the suspected commerical use message, etc.

Is the "backlog" now approaching 50 days?

TIA
