SPAR is the WORST!

Spar customer service is non-existant. Bought an off-milk at Spar Summerstrand. Tried to exchange it at Spar Main Rd Walmer and they say you have to go back to the original Spar you bought it from as they are all franchised?! This doesn't happen with other chains like Pick n Pay...wont be shopping at a Spar again, they have a lot to learn about decent customer service!
