Unexpected Order Message

[Peter_s]

Have received the following text out of the blue. What do I do as can't get to speak to anyone at O2 and this is really making me worry.

O2: Thanks for your order. Your SIM is on its way and will be with you in the next 1-3 days. To activate your SIM text SWAP to 20220

Morning all, thanks for the tag @gmarkj 

@Peter_s I’ll message you privately and look in to this for you.
