You can buy a pair from here:
PrimeABGB for ₹8398 (2x16GB) and I am pretty sure you can run XMP at 3000MHz and then just change speed to 3200 and they should boot just fine.
Edit: I didn't see that post from earlier. Still this is very good option. I have had very good experience on B550 Tomahawk with Ballistix kits.
Here is another option, 3600C19 Ripjaws V for 5K per 16GB Stick:
