Based on the comment that your output string is:
INSERT INTO #TempTable(Col1) VALUES('We didn''t understand, please resend, or type HELP and someone will contact you.')
You will need to escape the quotes surrounding the string, and quadruple quote the ones that should actually be quotes... Something like
INSERT INTO #TempTable(Col1) VALUES(''We didn''''t understand, please resend, or type HELP and someone will contact you.'')
