Appaling & highly unprofessional customer care!

Recently, I ordered a small item from ASOS. I've waited for it for almost a month and in the end I haven't received it. My experience with the ASOS customer care was most appalling. I spoke with just about an entire CC team and their fb customer reps (ie. each and every email or chat is responded to by a different person, repeating their automated responses blindly, without as much as reading customer messages or questions). ASOS customer care/fb teams are rude and highly unprofessional. There's no coherent internal coordination nor communication at all. Nobody follows up, nobody take any responsibility or ownership of cases. When asked to escalate my case or (after entire 10 days of back and forth messaging and a whole weekend of useless chatting) have someone in charge to call me (which seems to be clearly an option as stated on their website AND also proposed by yet another of their agents) NOBODY bothered to contact me on the phone. They just kept repeating their 'pre automated' texts, without looking once at my responses. I have NEVER had a 'pleasure' with such horrendous, beyond ANY standards customer service, EVER. I wouldn't (and won't) advice anyone to use ASOS services, ever.
