AIBU to feel upset about this customer services?

[Zeitgei5t]

I'm not in a good place mentally so may be making a mountain out of a molehill so wanted to get some opinions.
I live in a different city to my parents, I wanted to buy my dad something nice for Father's day as he's been supporting my mum recovering from her breast cancer op.
Tried to order some chocolate online, the web form wasn't working so rang customer services who took my order over the phone.
Yesterday my order arrived at my house.
Rang customer services to say that the order had arrived at my house not recipients. Advisor checked the order and it had been put through as my address even though I had specifically asked for it to go to my parents address. She said i should have not accepted the delivery but a) i wasnt home when it was delivered my husband accepted it and b) it didnt have the company name on the box and id ordered some other things so only realised when i opened it. I explained it was a father's day gift but she refused to either have it collected or resend order saying to ring back Monday as they would need to check the phone recordings and there was nothing else she could do. There were no managers there who i could speak to. I gave the name of the guy I spoke to when I placed the order to which she said oh he's very experienced, I doubt he'd have made a mistake like that (ie. Inferring I was the one that was lying). I was made to feel like I was the one in the wrong and that I was lying when it was their error.
AIBU to feel upset about this? I know it's not life or death but surely customer services could have done something?

I'd sort an alternative for now, then follow up with them on Monday to have them listen to the call (because I am stubborn and when I know I am right I know I am right). Once confirmed, have them refund you, then never use them again (and possibly a true review on Google).

If you know that you asked them to send it to your father's address YANBU. Sort it out tomorrow & complain.
Call your Dad & explain.

I've rung my dad and he's fine with it. I definitely told the address as I had to spell out my dad's name as well as go through the phonetic alphabet with the postcode. So yes definitely going to ring on Monday, wondering whether to raise an official complaint about the person I spoke to yesterday or whether that's just petty?

Are you on Twitter or Facebook? With big companies I find that I get immediate replies/ results if I message or post on their page.
You are able to type the facts (dates/times/nature of complaint) rather than speak if people make you flustered. X
