Missing item from my order!

I ordered 5 Items from the online sale on the 19th of January 2024. I received my order on the 25th of January 2024. There was an item missing so I tried to contact them on the 26th of January 2024, I called three times and there was no answer for over 26 minutes at a time. I eventually ran out of airtime so I emailed them hoping to get a response and resolution. I did not hear from them so I sent another follow up email on the 29th of January 2024 and today is now the 31st of January 2024 and I have not received any feedback from them. I am extremely furious at the service. I have paid for my items and I don't even have them all. This is the first and last time I deal with Pandora Online Shop.
