loading a csv file with embedded delimiters

I am trying to import a csv file using SSIS (2008 r2).

There is no header row in the file and one of the fields contains multiple commas therefore I am having difficulty in loading a small number of these records where the field contains one of more embedded commas within the text qualifiers (double quotation marks).

I have read a solution which is to make the text qualifier equal to a single set of quotation marks however on trying this it generates an error "The column delimiter for column 73 could not be found". This is the last column in the file  however I have already removed it from the import process as it does not contain any useful data.

Any assistance on this problem would be much appreciated.

thanks
