Product fail-management blames client

Two weeks ago I went to the store for can spray for ice buckets I was using for an event. I followed the suppliers instructions on the can and listened to the sales advisor in store. The spray lasted exactly 20minutes and started peeling from the buckets.

The following week I returned the spray and took the buckets with me to the store. They denied me any sort of help and I showed them. I wasted money purchasing the product that didn't even work.

The managers were arrogant and rude!! Took my half can without reimbur*****t. Kept then called and told me I should've used Primer which wasn't mentioned when I asked for help in store or on the can. I asked them to contact the supplier and get back to me. Instead the manager called to tell me I didn't use the product and I should've known to use primer.

As of today no feedback from the store manager.
