Bought a £20 SIM of Amazon (sold by Smarty). Then found out I had to activate it to use it. The problem is the activation page on the Smarty website doesn't work. Hours talking to support - no progress. Shocking level of service when you expect to be able to plug in a prepaid SIM and it just work. See someone else had similar issues a few days ago - so this is not a one off.

Update to your response:
"You have the option to activate our sims either through our app or website." - tried both and two different computers on different networks, none worked. Fix your website!
"Alternatively, our customer support team can assist with the activation if you provide them with the ICCID number" - did that, and they said I had to wait a day while it was escalated. No response.
