lack of service and feedback

I have used automagic revonia before and had bad service and have already reported bad service. I have then found out that the owner has changed so I gave automagic a secound change. Unfortunately no improvement. I went in last week to get my bumber fixed. I was then told that they can fix it rather than replace it. So I told them that can they do it in a day and they said yes. I dropped the car on Monday. I then was told no they need to replace so I said get the cost which it took them the whole day and 7 calls later of following up and demanding an answer. I had enough and went to collect my car undone. When I got there I had asked for a quote as the job has changed. That took 20 mins which could have been done in advance. I then accepted the quote and paid R500 deposit and made an arrangement for the following Monday which wad agreed to. On Monday I had to again call and be told the wrong part was ordered. And I will be called to come in on Tuesday. (Today) no call recived. I now demand my deposit back and will go elsewhere that wants the work. I want my money back and I will not accept any excuses. Will never touch automagic again.
