Quick response by customer service centre

I had an issue with a 2litre Pepsi. It didn't have any gas and it had a soapy after taste. I called the call centre to complain and they took down all the necessary information from the bottle and said they would post a voucher to me as compensation. They also requested I keep the remaining Pepsi aside so they could collect it and test it. They came the very next day to collect the defective product and to my surprise they sent a voucher for 3 × 2 litre Pepsi colas as compensation with their courier !! Thank you PepsiCo South Africa !!
