I have send a documents last 8days ago from Solapur to Kolkata(Pin-721603). But it was still not reached at Kolkata Regional head office(I have inquired by telephone). Many times I called Regional & Solapur office of Maharastra but no solutions was came. Online tracking report was not get any information for this docket copy.
Then today I was personally visit at Solapur where documents was booked but they didn't get any information. After that I was called them for the status but they answered like a crazy that " This courier was booked the documents from First flight courier to other courier center like Maruti at Pune Regional office''.
The documents was too importance(All documents are original & most importance) that my brother will be not attending his importance exam & my relatives are moving 2/3 times at your local first flight office at near my home. Docket no is M[protected].
We are suffering very big problem for that. For the first time I have facing a lot of problem from your service. I have actually fad up for this blinding services.
Now advice me how can i receive my original documents at proper time & proper way.
Please look into the matter on priority basis.
