Kindly refer to the letters mentioned above. Kindly refer to our guidelines issued
earlier on the subject vide our letter no. ITPC/IOBAS/33/2006-07 DTD. 09-08-2006
(copy enclosed). It is observed that we are finding it difficult to settle the disputes if they
are forwarded to data centres without preliminary examination by the Circle IOBAS cell
as well as when there is a delay of 6 to 8 months in sending disputes to data centres. This
has resulted in accumulation of disputes as well as delay in settlement of dispute cases.
To facilitate quick resolution of the dispute cases, circle IOBAS cells may please check
the points mentioned in Annexure before sending dispute to data centre for reconciliation.
It is also requested that disputes should be forwarded to data centre within one month of
issue of invoice /outgoing statement.
You are requested to kindly issue the instructions to the IOBAS Cell to follow
these guidelines and help us in resolving the disputes early.
