Income Tax Department — not received my refund ofrs. 16995/-

Sir
I'm a retired employee and senior citizens and regular tax payers. This year[protected] my return shows rs. 16995/-
I received intimation from lncome tax dept bangalore that your tax demand out standing for the a-y 11-12, we will adjust this refund against that outstanding. I object and sent a letter to them and enclosed form 16 and i t return copy how ever they have not taken care and l recd sms that your refund amt is adjusted against your o/s demand it is injustice to me. I already paid taxes on that year and twice they are recovering
Please help me
