Sun Tv — pin code - incorrect way of pronouncing

In suriya vanakkam, the anchors are pronouncing pin code as "six lakhs twenty eight" instead of six zero zero zero two eight. I have pointed out this in mail many times to those anchors, many times. But they continue the same way. The anchors should be # in not responding to my comments. I have seen that even the aged person in naattu maruthuvam does the job well.
