No after sales service!

I have been a loyal customer ordering Nestle Dolce Gusto pods regularly. My last order received has been incorrect and I have been calling for more than a week-different times of the day, holding on until being cut off. I have sent e-mails as instructed, I have sent whatsapp messages, I have left voice notes but no one bothers returning the call or replying to an e-mail or WhatsApp message. I find this extremely frustrating and unacceptable. No after sales service.
