Poor service and bad attitude from Grant

My dad went into fourways branch on wednesday 29 april to order a battery and switch for the offroad bike. Grant had to order it and advised he will phone my dad when it came in. Monday my this week my dad went in and Grant advised that stock will be in on Tuesday and that he will phone him. Wednesday my dad phoned Grant Again who told him stock is on its way. Today i phoned Grant who could not remember anything. After carefully reminding him Grant advised that the stock came in 30 minutes ago. He was unable to give me final price as the stock was not on the system. He will phone my dad tomorrow. After confirming this i said thanks and that will be my last dealing with big boy fourways. Grant's immediate respinse was well in that case the battery and switch will not be available for us to buy. This from the branch manager. Disgusting and pathetic customer service.
