Caller: They just called and hungup

Based on the above comment it may be a courier

Got an SMS saying "Hi ***** what is the address". They spelt my name wrong, didn't use any punctuation, no question mark... I don't have many friends who don't know how to write properly, even in an SMS. They didn't say who they are. I'm not expecting anyone to visit, nor to send me a parcel, but if I had been expecting a visit and if I were naive, then I might have assumed it was someone I know and replied with my address. They already have my phone number.
