WORST Customer Service/Quality of GOODS below par

WORST experience EVER!!! I logged my initial complaint on 19th July. 2 months later and I am still waiting for a refund or replacement of below standard Nappies. I bought 2 packs of Dry Comfort Size 4. Looking on their Social media page I am not the only one who had this problem. Call center based in the UK makes empty promised regarding courier pick up and voucher drops off's . 2 MONTHS is ridiculous , at this rate my son will be potty trained before they get their act together
