Hope you are doing good,
First thing is to try to upload images of the product with the clearly shown logo of your brand.
Secondly, See you can get TM within a month in most cases in just a week. For registered mark, you have to wait for a year. So i would suggest you to get TM immediately and if you see any seller selling your brand of products then you need to inform them that they are violating your Trademark Rights.
I would suggest to get a letter from your CA in which you can mention that you own the trademark and when you have received it along with your trademark number.
In this letter ask CA to mention all the clauses which one is violating when they are sending your brand of the product without informing you.
And upon any TM violation case, you can directly send this letter to the seller and threat to Sue his, understand this, as per Indian laws once can’t sell your TM of product and he will be fully liable for all the damage he is making to your brand.
