Poor quality Scotchbrite

I have been using the Scotchbrite scouring sponges for many years. The sponges in last 2 packets that I bought, came apart after the first wash. The scouring pad came off the spunge. We always use sunlight liquid and warm water. I sent a complaint to the 3M ( 14 November) head office and received a mail saying the will contact me. I have not heard anything since then. They are obviously not interested to complaints.
