Umkept Promises

My wife bought me a Nespresso Essenza bundle on 25 November from Yuppiechef.com I received the machine on 29 November and registered it immediately online. I received an email to say that I will receive my coffee voucher in 72hrs. That did not happen. On Monday 4 December I sent a follow up email and was told it was escalated. On 7 December I called and again was told it was sent to e-commerce. I followed that up with two more emails and another phone call on 12 December. The agent then finalised my registration and profile and advised that I will receive my voucher in the same day. I waited 24hrs and still have not received my coffee voucher. I am disgusted in the level of service received from Nespresso. My wife has been a Nespresso client since 2014 and never have we experienced this kind of service.
