Samsung mall of Africa - Bad service!!!!

I went in to Samsung store Mall of Africa to book in a phone with a broken LCD screen, to get a quote for insurance I was told it would cost R250 on top of the R2500 to fix the screen. I later decided to book in it and was assured it would take 3 to 3days to complete and I could collect it then. 5 days later I arrive and the screen is not done! The gentleman at the repairs looked confused when I asked about the phone I had booked in , it seems it had skipped his mind and later came up with the excuse that they did not have screens and then asked when can I come again to collect the phone? I decided to pay before I left, the girl at the cash point said 'well "Sandton is not that far" belittling my plight when I mentioned the phone was still not fixed. Other consultant were chatting loudly while eating a bag of chips on top of the counter displays where cellphones and other Samsung devices are displayed. the lack of presence and concern that they had for customers, despite their nice tone of talking, was disappointing. I walked away a disgruntled customer. very poor service. I will be returning today to collect my phone hoping I do not have to repeat this admin again in the future!
