I recently had the unfortunate experience of dealing with TheMangaStore, and I must say, it was nothing short of a nightmare. Their complete lack of customer service is astounding. I reached out to them regarding a T-shirt exchange due to size issues, and despite multiple attempts, I received absolutely no response.
To add insult to injury, their exchange portal was conveniently closed by the time they finally got back to me, effectively trapping me with an ill-fitting product. This level of negligence and disregard for their customers' needs is truly disheartening.
