Not honouring a special and non-existent after sales service

I am very disappointed with Nespresso advertising a deal for cyber Monday and only delivering part of the agreement. The special stated to purchase 25 sleeves of coffee and receive a free hamper. I did the purchase and the coffee was delivered without a hamper. After emailing and logging complaints on their website, I have not received a single response. I feel cheated. And despite being a customer that spends a lot of my hard earned cash with Nespresso, they don’t even respond/ acknowledge any of my complaints. I will definitely not fall for their ‘spacial offers’ again either. You would think that with an elite coffee brand like Nespresso, comes an elite customer experience. THINK AGAIN
