Bests & Worsts Reviews from Amazon

I really didn't want to write a bad review but there is no way to contact the seller either through the Amazon app or the company's website. I bought a batch of 36 fog chaser k cups and several of them are delaminating in my Keurig, which causes the coffee to spill out. I have been using these for a year without problems b so I'm wondering if I just received a bag batch.
