Failing delivery & poor excuses

I couldn't fault Royal Mail services,but recently I had trouble with my deliveries and that not because of pandemi. Their new policies seems to not protect their clients, I'm just entangled on this Royal Mail web so nothing can be done. A next day delivery was just despicably handled, so I was asked to go to collect my item. Ouch ! It sounds to me as discrimination and when raised this through customer service today, the lady seemed pretty nervous. I paid for my delivery but I need to make a claim through seller even if are my money. I just wanted to know why the postman could deliver to my next door on the day my delivery was scheduled and why I have to go to collect my item and another delivery attempt didn't take place. They say that no one was home,but because of my condition I don't leave my house. Card wasn't left but the customer service persuaded to receive a card before to go to collect my item. Conclusion, just a massive lack of respect and no -one from Royal approached my property last Saturday, otherwise a card would have been left. Their excuses are just poor.
