I should add it gets moderate but indirect sunlight. For the dead/dropping leaves, I cut straight across the bottom of the leaf as close to the soil as possible.

Pls share pix.

Does the pot have a hole in the bottom? What kind of soil are you using? This too sounds like overwatering.

If you never watered, the Seller did. Was it from a Nursery or a Big Box Store? Any chance you can return it to the Seller?

So 1 watering in 4 months rotted your plant? Something is VERY wrong as that is just not normal. Have you taken it out of the pot to check the roots?

Soggy can't happen from underwatered, that yields dried out leaves, sometimes crunchy, not soggy.

Could also be root rot coming from underneath leading to soggy / mush. Perplexing.

Have you considered cold damage?

I'd be surprised if it was cold damage as it is in a protected part of my apartment, which is heated.

'Soggy & bad odor' = rotting. Maybe plant had serious fungal disease before you bought it? - I am just speculating, since these are usually very tolerant plants.

Thx for the pic, I would have liked to see the soil & base of the plant, that can tell us a lot. sorry but that partial leaf doesn't tell us anything,

Agreeing w/ Rina, foul smelling confirms it's rotting & that pretty much marks it as a goner.

Some places like Home Depot have a policy of refunding for a year if the plant dies. Depending on where you bought it, I'd take it back & ask for an Exchange or a Refund. What have you got to lose? 4 months isn't long after which to return a plant.

In general, I'd much rather ask, than assume something isn't possible. If not possible to refund of exchange it, they'll tell you. There's nothing to lose by asking.

I have a collection of Snake plants and I rarely describe them as easy, hardy, resilient, tolerant, etc like most people do. Some varieties are just plain finnicky and die for no reason. When they die it's usually like this, by one random rotting leaf at a time. I have two plants that are amazing and I've gone through quite a few other varieties that haven't done nearly as well. What has worked for me? Idk really. When I buy them from the big box store I immediatly take them home and rinse off all the soggy peat from their roots and let them dry. Then I pot them using
orchid blend mix (dont buy the miracle gro brand, theyve all had fungus gnat infestations recently) which is basically just pieces of bark and the pots have to have drainage holes. So really the water just runs over the roots, never actually sitting on it. They like to be root bound, whenever Ive tried putting in large pots they suffer. I only water every couple weeks. Ive attached a pic of my good variety (I have two of these). They're beautiful and constantly growing and reproducing but, like I mentioned before, other varieties have died with identical growing and care methods. Luck of the draw maybe? I'm still trying to figure it out.

I am sure there are some 'finicky' cultivars,-varieties, but from what I read (and my limited experience with Sansevierias since I have only few and I did manage to kill one - Hahnii marginata) typical Sans that are for sale in most stores are very easy to grow.

Good drainage, good air flow and appropriate light - they don't need strong light as many other succulents do - and they usually grow well. I grow mine in gritty, but am sure other substrates work well as long as they drain well.
