Can't get another test after I had one

[CometCupidDonnerBlitzen]

I was wondering if anyone else has had this problem. I had a dry cough early last week. I took a test and it came back negative. The cough vanished as quickly as it came on and I thought no more of it. Yesterday I woke up with a complete loss of smell and taste. It's still gone this morning but no other symptoms. I have just tried to order a second test and it says "You have recently placed an order for a home test kit. We are not able to process another request at this time."
I don't feel unwell at all. Is it possible I tested too early? Is there anyway I can test again or do I just have to isolate now? Not sure what to do. The only other time I've experienced a loss of smell/taste has been with a really heavy cold.

Have heard of others having that problem. Ring 119 and ask them?

I couldn't get a home test online for my niece as they couldn't verify her identity because she's a child. I called up and explained and they sent one out, its worth a call to 119.

Yep, DD was sent home from nursery with a temp, we ordered her a test and it came back inconclusive. THE ACTUAL TEXT said we had to order another for her, but we weren't allowed because she'd just had one. She wasn't allowed in to nursery without a negative test so we had to keep her at home, still pay for nursery and whilst both of us were trying to work. It was a nightmare. DD's temp went down within 2 hours of her leaving nursery and she was absolutely fine in herself.

To add, we rang 119 after it wouldn't let us order another test online and they were having the same problem and couldn't order one for her either

Thanks for the responses, I phoned 119 and spoke with a lovely lady who was able to override it and order one for me. No idea why they weren't able to do that for your daughter @WhenTwoBecomeThree.

Fingers crossed it's nothing.
