Faulty website, rude consultants, after six weeks, documents still not uploaded.

After a great experience with you replacing my iPhone this week, I am very disappointed in your consultants and Online Vault. I cannot upload proof of ownership for my iPhone, my fiance's phone and my engagement ring. The website does not allow me to save the documents. I have tried on different devices and browsers. I have asked since 3rd January for a consultant to upload them for me. i have emailed countless times. My biggest concern is that if something happens to those things, you will not pay because YOUR vault doesnt work., The last consultant was so rude to me and actually said it is "impossible" for it to not upload because there is no error message but there is very clearly an error in the coding of your website. I even offered to take a video so she could see what I did but she was not interested. I am very scared to know that I might not be covered because of something that is not my fault and I would like to make it clear that should any future claims be denied because of YOUR faulty website, I will take all manner of legal action since my emails and instructions have been ignored for almost two months. KINDLY UPLOAD ALL MY PROOFS OF OWNERSHIP AS I KEEP REQUESTING
