Cadbury after sale

I purchased a Cadbury whole hazelnut 80g chocolate at a local shop when I opened it to enjoy it was white. I wrote Cadbury an e-mail as this was not the first time I purchased a Cadbury product from the shop to get this result. I was so surprised to get an e-mail back from Cadbury the next day explaining in detail what caused this with a R40.00 voucher sent to my phone. I realized that this was not Cadbury's mistake but the supplier the shop purchased from. Keep up the good work Cadbury, they take pride in their product,
