Terrible customer service, not honoring so-called warranty

My 93 year old mother-n-law bought a pair of JCP Leathers' (previously JCB Leathers) sheepskin slippers from Takealot. After 2 months they started chaffing her on her toe. Inside the slipper a very hard object could be felt. After returning the slippers to Takealot, they said they won't exchange it, although it felt like a manufacturing fault. After contacting JCP Leathers directly, they said they will replace the slippers. Anni assisted very kindly to return the slippers and send a replacement. She also advised that upon inspection there was indeed a bur lodged in the slipper and thus a manufacturing problem that unfortunately was not picked up by quality control. 10/10 for JCP Leathers for customer service, 0 for Takealot.
