@Mac6 I don't know what number you called, but you need to speak to customer service again.
Call 202 from your mobile or 0800 032 1402 from any phone. Both are free calls.
When it comes to the reason you are calling, stay silent for 15 seconds and you will be taken to the keypad options.
Press 2 for Everything Else
Press 5 for More Options
Press 7 for Anything Else which will put you though to someone.
Say 'Upgrade', 'Lost/Stolen', or 'Fraud' if the suggestion above doesn't get you through.
Best time to call is 8 am.

Other numbers available are here. All are free calls, apart from the 03 prefix, which is a local call charge: Guide: Coronavirus Community Help and Support
