As mentioned previously by my colleague, we do indeed have UK contact centres who take calls from our customers.
What you may have been told is that there is no direct UK line which is true. When you call us and select the relevant options for the department you require, you are routed through to the next available agent so your call is answered as quickly as possible.
I can see that you're currently speaking with another colleague regarding a SIM issue. If you are having any other issues and need help, feel free to post about them here and we will do what we can to help support you. There are some things we're not able to help with such as package changes but for the most, we are able to support.
