rotten camembert cheese

I sadly had no choice but to go to woodmead pnp yesterday, after promising myself I would no longer support them. I bought a few items including a camembert cheese. When I opened it last night to eat it I smelt it was completely off. It's revolting. I will.be returning it today and they better give me my money back and I expect a voucher for this inconvenience it has caused me. A R25 cheese now costs me R100 for me having to drive up and down to return it. What will PNP do??? Probably nothing. They must get some tips from Checkers where staff is friendly and management actually knows how treat and keep customers.
