Poor food quality

I am loosing my patience with Woolworths SA on how they handle customer complaints. Logged a complaint of bad customer service and the food never met Woolworths standards. Received the first reference no: WW-228486-D3Q9J4 which till date hasn’t been resolved. Received an email saying that they will send a voucher within 3 days, sadly they sent the voucher to the wrong number. Wrote another complaint with ref:WW-268736-w1R7S8 stating that my cellphone number was incorrect and the correct number is *** till date I have heard from them. Disappointed in the way they handled this matter….. it has been 6 weeks now and still this matter hasn’t been resolved. Please assist!!!
