No service on data share activation since first enquiry 13/08/2021 after 10 engagement with them

In addition I sent an email on 19/08/2021 with a complaint reference Automated Response - Enquiry Reference Number ***.

To date nothing has been done.

I called in again 25/08/2021 and they had still not activated my data-share.

Is there no way to get proper assistance?
