48 support don't generally monitor or respond to posts here on the Community Forum so they're unlikely to act on your request.

If you need to contact 48 support about this then see the links in my signature below.
By the way, it's not a good idea to post personal information such as your phone number in a public forum like this where anybody can see and use it.
