I get texts once in a while for services. I replied once and it was a big joke. It sounded like it was leading into a scam. I never gave any of my information thankfully. The sender turned the whole conversation from pricing and scheduling to asking me to wait until she was out of the hospital due to lung cancer treatments she was recovering from. I never responded and put them on my block list. Very strange.
Yes, they will ask you if you take credit cards. Of course they can't talk on the phone (because you would know immediately that they are foreigners). Then they will pay your price and add extra for you to pay someone else, driver, preacher,, whatever. The money will have to be sent by untraceable means such as Western Union. Then the credit card charge gets reversed and you are out the money and the fees.
