Today's Sausage Rolls just all pastry

Have an aftercare for boys and we been buying Today's Sausage rolls for the past 12 years. It's on our menu once a week. I am a pensioner therefore its money well spent and the boys enjoy them. On a few occasions I found that some of the Today's Sausage Rolls had no filling. I contacted the Customer Care Line and they ensured me that they will look into it and said they will send us some vouchers. These vouchers never arrived and we followed it up with them and informed we will get back to you. We asked if we need to keep the EMPTY Sausage Rolls as proof and they said no. This all took place more than three weeks ago. Their response time was to be 10 days. I call Heinz offices and was informed that Mr Simon Joseph will take care of the matter. Phoned them three times and was informed that he will return my call. This never happened and therefore this complaint.
