Oh I do certainly understand your frustration. I hate to say this but if it has been 70 days, I think that is an excessive delay, and I would start to wonder if the form had actually been sent off, or whether it is lying in someone's in-tray. As far as I know it isn't possible to contact the police who carry out these checks because once the form has gone off, there is no way of knowing exactly where it is if you see what I mean, and I am a little bit sceptical of the sws saying they have contacted DBs and made it "urgent" - we could certainly never do that when I was working in Children's Services.
I have been retired since 2009 so things might have changed but I don't think so - my son recently changed jobs and needed a new DBS check and after a month and nothing had happened he tried to contact the office where he thought they were dealing with the check (not sure which office) but was told that there was no way any information could be given about when the DBS would be returned, nor any way of expediting the request. They told him it was 4/6 weeks but they had a maximum time for "turnaround" of 60 days. As it was it was returned in 4 weeks.
The other thing is that all LAs may well have a different procedure for sending off these DBSs - and I only know the system we used - the completed form went to Human Resources and they sent it off - but I have to say I don't know where to - it didn't really concern me - I just wanted the result.
What was the procedure when you completed the form. Did you complete it and send in your ID docs to the SS office to be checked - if so were your docs returned, or did the sw complete it and saw the docs and you signed it and the sw took it away. I always used to complete the form and see the ID Docs and get the applicant to sign as a lot of people were put off by these forms.
I know you are in a tricky position and it may be that your LA does have a way of checking where the DBS is in the system and can ask for it to be dealt with urgently, but I do somehow doubt that.
I think you need to start asking questions about who sends off the form and where does it go to, and how can they check where it is in the system. A good word to use is puzzled when you mean WTF (!) You could be puzzled about a 70 day relay because it was your understanding that the maximum time allowed for turnaround of these forms was 60 days. Maybe google and you might find a reference to this 60 day max as I think it's a government requirement. You could suggest they give you the number of the office they allegedly phoned and then you could make enquiries, to save them time...........be interesting how they respond to this.
So sorry to be so sceptical but I worked freelance for 5 years after I retired and I carried out assessments on foster carers and adopters for neighbouring LAs and in one case (well quite a lot of them really) the sws were a bit hopeless and were so overloaded with work they couldn't think straight, and I remember one case where I was badgering the sw to complete the forms for the checks (they were called CRBs then) but served the same purpose, and eventually he did them. Weeks went by and the applicants were just waiting for the sw to contact them and after about 3 weeks I contacted him and asked if the forms were back.................there was a pause and he said "back from where" and I said "from wherever you sent them" and he said "Oh I put them in the file.............!!"
I rest my case!
