I had one quite a long time ago that really pissed me off. Usually I block them and forget. For some reason, this one set of scam messages really pissed me off. So, I spent 20 minutes searching for car insurance, windows and solar panels online. I gave a fake address and the scammers mobile number. Then I opted in to all the marketing SMS messages. Until they binned that sim card, they'll have been bombarded with adverts from companies that never stop trying to contact you.
