Bad service

On the 22nd of September I took my phone to Vodacom Southgate for repairs, I was told to bring it on the 25th as they don't book phones on Saturday, to it there on the 25th where I was told to write my details on a piece of paper, was told I will get the phone back in a week's time or so. on 6 October I went to check the phone, I was told it was not back yet and I should write my contact details on a piece of paper again.On 20 October I went to the shop again, this time I was told that my phone was not booked yet, I was told to write my details on a piece of paper again. There were 2 exact phones which they did not know who they belonged to, I had to check which of the 2 was mine, was told phone will be fixed and I will be called by the 23 October, I went back 24 October and was told that it doesn't just get to repairs and get fixed, my question was why was it not marked as urgent.

The 1 Saturday they couldn't book phones and the other Saturday it was booked, how is that.
