Disappointed with quality (and customer care)

Im so disappointed with Huggies. So here I am venting on social media which I didn’t want to do but your complaints department gave me no choice. In 2013 when I had my first daughter, I had no issues. In 2021 the Huggies Gold and the Huggies Dry Comfort ranges have leaked on numerous occasions. I made the complaint and on the 8th of June I received feedback containing a whole essay stating what I must do. I sent them pictures on the 22nd June and today 14/07/2021 I decided to follow up only for them to advise “We are sorry to inform you that we were unable to verify your complaint. Please ensure that the whole pack is viewable including the reference and is free from any obstructions. We apologise for the inconvenience.” So, I called, and they asked me if I still have the nappies, my reply was I used them because I was not going to let my money go to waste and some of the nappies were gifts. Seriously who keeps the original packaging of the nappies. After a long chat she advised I need to give my bank statements as proof that I bought it. I really felt like I’m being interrogated and for what? Nappies?! I still have some of the size 2 that I kept but they want receipts of when I bought it. Who still has these when you bought them before the baby was born? The way they were asking questions it was like I was lying. Do you want me to draw blood, or you want DNA samples? I just did not want another parent going through the same thing. My daughter would wake up 2-3 times at night because she was soaking wet, and the nappy was not that full. Running after Feedback is not my priority, as I have a baby to take care of. I just expected that putting my faith in your product would help me but instead she was having sleepless nights.
