Revert to one PAYE Coding Notice

In prevous years I received one PAYE coding notice even though I was in receipt of more than one small pension. I do not pay tax. This year I received two coding notices as my pensions come from different tax areas, and even though none was due tax was collected from my pensions.After numerous  telephone and six coding notices I am still wating to see if the tax will be refunded or do I start the above again.  

Please bring back  "one PAYE Coding Notice uniting all income under one tax office

Why does this idea matter?

It would save a lot of extra work by the Inland Revenue not only in working out different tax demands but also in postage and paper and less distress to the public when theyTax office get it wrong and it is difficult to correct.
