Sick and tired of vodacom Cresta

I brought my phone for service at vodacom Cresta shop, instead of fixing the phone they replaced the device with a new one. After I collected the phone just found out that it doesn't vibrate and booked it for service. After few days I received an SMS that my phone has been fixed and ready for collection, to my surprise when I reach the shop was told that it's not fixed and must re-book it . They didn't even apologies for the inconvenience cause and worse part I waisted money,time and petrol to go the shop to find out that the device is not fixed. vodacom Cresta owe me a big apology because I used money to go Cresta for something that's not ready. I want them to give me money I used for petrol, I even bought bis that's not working now. I am running at a loss because of poor customer service .
