No proper system in place.

I am utterly disappointed with Pioneer Foods. I bought their prunes in August which turned out to be fermented even though their expiry date is still far. I sent them an email, received a call which promised to revert. I have been chasing them since, they keep telling me they will revert. I have requested emails to that effect, they tell me they communicate only by telephone. For a big company they should have proper systems in place to deal with dissatisfied customers, but I guess they don't care. I have decided to throw away the 500g packet since I am not being taken seriously.
