Hi ​@DarrenSm 

Please check the below:
Settings > About Phone or About Device > Status > My phone number.  Some Android phones will have SIM or SIM card status listed within Status.  This is how you will be able to find the number you are using on your phone and sim. if using Message App,  Change the phone number associated with the Messages app:  Open the Messages app.  Tap More  then Settings  then Advanced  Select Phone number  then edit the number to the correct phone number associated with your SIM card.  Tap OK.    If still have issue, remove the SIM and reboot the device.  Then re-insert the SIM and check if its updated the correct port number in Phone settings.    Still have the same issue after rebooting  then advise try the SIM once in different device and  see while sending text does it shows temporary number or port number.

Already tried all this and tried them again after reading this post. Still nothing.

And it gets worse! Tried to call them to hopefully speed the process along a little. Unfortunately, trying to speak to an actual living person at iD is harder than drawing from a stone. Wasted around an hour trying to figure out how to get hold of someone, told them my whole story and that I’d spoken with an online chat representative yesterday, who informed me someone would get in contact with me, within 48hrs. Having to wait this long alone is absolutely atrocious and just a delaying tactic to make it harder to cancel your contract! Other companies can have you talking to tech support with 5-20 MINUTES! Never mind 48 HOURS!

Also, all this information has been forwarded to OFCOM.
After the situation was explained, she then went on to tell me, that the wait time for my issues to be resolved was 74 HOURS! Bearing in mind, this was 24hrs after my first contact! So, for those keeping track, there should have only been 24hrs remaining to wait! Now it’s 72hrs - or cumulatively 96hrs! FOUR DAYS! OFCOM needs to shut this company down!

And I’m not done yet! After being informed of this new wait period, I requested to speak to a supervisor, was told “none available” - classic bad-callcentre tactic, I’ve worked in more than a few that falsely claim this and inform their staff to tell the customers this. I asked again and she decided to hang up the call on me! If I’d have hung up on a customer, I would have been sacked on the spot! This was the complaints line! Hanging up on an already frustrated customer, without their consent!

And the abysmal customer service continues. After speaking to them yesterday midday and being told I’d be contacted in 48hrs, I decided to call them by phone to try and speed things along - I’m missing very important calls! Explained all the above and was told I'd have to wait another 72hrs! Told them this was unacceptable and wanted to speak to a supervisor/manager, at which point they went silent and hung up on me!

I should also point out I tried to post this a few hours earlier, but apparently their moderators like to censor any signs of complaint, they can’t deal with… Unlucky for them, this whole message is copy/pasted in a notepad and all other social media channels.
