Bad service

I have a contract phone for my daughter with Vodacom. My daughter took in her phone in for repairs on the 16th of October 2018 and it was taken in by Sheila Louw. Four working days later, they called her and said her phone can be repaired and it would cost R1255.50. We allowed them to repair it and was told that in 3/4 working days, the phone should be repaired and sent back to the store. 7 working days later, she called and they said it wasn't ready yet and that she should call on Tues or Wed. On Wed (7/11/18), they told me, when I called, that they could not repair the phone as it was beyond ''economical repairs''. On Thurs (8/11/18), my daughter went to collect the phone and they said it wasn't back yet and that they would call her to collect it. She called them the following Mon (11/11/18) and they said they would call me back later that day; but they didn't, as they often said. I had also been calling them and getting the same respond. On Tues (12/11/18), they gave me the number of the repair store. I called them and received no answer. The following day, Sheila called my daughter back after she had called the store, and said that her phone was in repairs and that we approved it. She informed Sheila that she was correct but that had been before I was told it was ''beyond economical repair''. My daughter asked them to have her phone ready by Friday, as she was leaving Cape Town early on Saturday morning. On Fri (16/11/18), she called them and was told that Sheila would call her back. She called and told my daughter that the phone was still in repairs and asked if there was a Vodacom store near where she would be going (Johannesburg). She told her that there was a store and she said they could try bring it to the store but she wasn't sure how the payment would work She said she'd call her back after she had found out how everything would work. On Wed (21/11/18), my daughter called them and was told Sheila would call her, but she never did. I called them on Tues (27/11/18) and they told me that Sheila wasn't available and she would call when she came back from a meeting. She did not call back. In the call, we did inform them that we would be taking action. The most annoying thing about this experience was that every time we called, no one could give us a straight answer and they always promised to call us back. Please help us to find the phone and they should courier it to my home as I'm tired of the shady service they have given me. One minute they phone can not be repaired and one minute they are repairing it. Their contact is ********** 444
