Im so annoyed by the incompetence of staff at take a lot

I’m a take a lot customer and this time they have failed me. I ordered baby formula which is S26 0-6 months which has a red 1 next to the months. I received the wrong formula delivered to me. My baby is allergic to the formula which was delivered and I went online to request return. I did not receive assistance at all and what pains me is the fact that they delivered a product which I didn’t order and now I had to go buy small formula for my baby since she ran out of formula and I have to give away this wrong formula delivered by take a lot. I basically lost about R400 from take a lot and no one cares to help and it’s their fault for sending wrong formula to me
