My brother name is s barathkumar. I was applied for anna university counseling on tnea 2019 for my brother. Application number: 223730.
Then we choose bannari amman institute of technology (Tnea counseling code: 2702). At the same time, he had been applied for b. Tech on tanuvas and he got selected. So, he didn't join any college under anna university. After one month, anna university offers refund newsletter in their counseling page for those who didn't joined the selected colleges. So, i applied online and posted that xerox copy to the anna university through speed post (Et[protected]in, et[protected]in) dated on 13/11/2019. After two days, our post has been reached their hands and i confirmed it by anna university official's telephone [protected] and [protected]. Now it almost 5 months over and we didn't have any response from that team. They only said, "it has been processed tomorrow and you will get refund on this week". I am only hearing this news for past 3 months and didn't receive any refund.
