Selling Goat meat advertised as Lamb

Spar Malmesbury Butchery/Meat department may be one of the poorest currently. The butcher, I assume, does not know how to cut meat or distinguish between Lamb/sheep and goat. Yesterday, I bought a so-called half a lamb for braai, only to find it was goat meat. (Tough as hell). What a waste of money. A few times in the past I went there to buy "T-bone/Club steaks, just to find that the cuts were so uneven, thick one side (30mm ending at 7mm) Conclusion: Either the butcher is incapable or not qualified, or they just don't care if they waste the meat customers have to buy. Their cashiers are equally rude. Being a Spar shopper for more than 20 years, this is the worst experience lately.
