I have purchased (ORD[protected] Mamy Poko Pants. The material I received is duplicate and not the original one. We are using this diaper for last 4 years so we have good knowledge abt it's general quality. But this time the quality is totally different. The package however was alright but the material inside was almost not usable. Every time we used it it leaked within 1-2 hrs. Grofer doesn't respond to the complain.
Pls do needful.
