Toyota Woodmead *********** staff

Serviced my Toyota at McCarthy Woodmead branch. Find staff not helpful and highly confused. Fan belt in my car needed replacement. Agent asked me if I want to replace part. Gave her the go ahead. They did not have stock so she had to place an order. Informed that she would place the order and call when part arrived. This was in January. Never received a call. Called in March and was told part never ordered and agent no longer works there. I was meant to pay for part before it is ordered. Why did she not know this? Poor training? Took very long to attend to me when I went to pay. Workers said they had already served me. Mistook me for the other Indian client in front of me. Paid for part Friday , was told would arrive Tuesday.No call. Called the following week and was told takes three weeks to arrive. Three weeks passed still no call. Called again to speak to manager. Craig said he would call back to give managers number. No call. Called again and got through to Brandon who helped me and informed me there would be no labour cost. At the branch agent tells me there is a labour cost. Staff highly confused, do not know how to deal with clients. Please investigate.
