Staff don't know their products

Staff don't know their products, i recently bought a biltong maker from game stores Umgeni Durban, when i get home i see on the box it clearly states ( No bulb included) so obviously i need to purchase a bulb so i phone game to ask them if they sell the bulb and how much is it, and the staff member that i called tells me to return the product as the bulb is missing, i called 3 times and spoke with 3 different people including the manager and everyone is confused clearly not trained. so i decide to call makro as they sell the same product and i got the answer i needed in under 5 minutes including price and product availability, although makro is slightly more expensive than game i rather buy from makro as they a well trained and fully staffed. I will never buy from game stores ever again, the amount of airtime i used to phone game was a ridiculous waste.
