Worm in flour

On the 26 January I did shopping at checkers and purchased a promo deal on Pioneer Foods Specko rice, maize meal and Saska flour, please note I never use Sasko flour (brand loyal) but the deal was good and I decided I'll take it. This past Sunday I wanted to bake and had to strain the flour . I noticed a white ball and assumed it a clot but it was a worm, I checked the expiry date then release checkers was selling items that are close to the expiry date 25/03 I use flour for about 4-5months and it was already heading for expiry. I logged a customer complaint on Monday waiting since Monday for feedback!! Do they expect a scene at the store??? Also I inform the customer care at Sasko no response
