Can I change the mobile number you gave me as I’ve had problematic calls
yes you can do this.
Give customer services a call (free call 789 from your mobile), explain the problem and they will be able to assign you a new mobile number.

You can certainly change your mobile number due to this and I'd love to help.
I'll pop you a personal message and we'll take it from there.
