Bad Customer service

MTN Lenasia Trade route Mall The is a stupid can't with **** silver tooth in this store called Riyaaz .I was buying airtime from the store with a R100 note and this son of a gun told me he does not have change i must go and look for a change and come back and buy airtime. This stupid boy did not even try to ask his colloquies for change .And as rude as f**k when i was leaving he was yelling in front of the customers. That nonsense of boy needs discipline. He must write me an apology .That was pure bull sh8t
