Obviously they think nothing of the sort and are just randomly spamming, even to mobile phone numbers registered with TPS. Given that their pitch is based on a lie, it's likely that the whole outfit it some sort of scam in any case.

If you get one of these, you should forward the spam and the sender's number to your carrier. In the came of T-Mobile, O2 and Orange the number to report to is 7726 ("SPAM"). Vodafone customers should use 87726 ("VSPAM") and Three customers should use 37726 ("3SPAM"). Hopefully the carriers will act if there are enough complaints.
