Wrong visa dates

So I'm going to India 1st March - 16th March. I applied for my evisa yesterday, and it came through today. But it says that it's valid from today for a month. Which is wrong. Im 99% sure I put the correct dates in last night. It just doesn't make sense I've emailed them but no response yet. I've read online they're not very helpful with responding to emails. I don't know what to do. I go in just under 3 weeks. This is what came through in the email.. Application ID :- xxxxxxxxxxx Passport Number :- xxxxxxxxxxx Application Status :- Granted ETA Number :- xxxxxxxxxxxx Nationality :- UNITED KINGDOM Visa Type :- e-Visa Service Name :- eTOURIST VISA No. of Entries :- Double Date of issue of ETA :- February 11th,2020 Date of expiry of ETA :- March 11th,2020 Visa Processing Fee Paid (Excluding Bank Charges) :- $25 e-Tourist Visa Validity period is 30 days from the date of first arrival in India.
