Apple iStore PATHETIC SERVICE

I booked in my device for a repair and instead of a repair, i was replaced with a device which i was told is new and paid R1500 plus for, however could never use it due to sim reader being faulty. I had to return the replacement device (and this was within 90days of having received it). I was quoted and asked to pay R7000 plus. This is by far the most disappointing experience i have had with a cellular brand. Highly ********* that iPhone a supposed reputable brand issues devices of poor quality but no accountability, no communication from repair centre just repeated emails of quotes sent. After expressing my dissatisfaction at the istore where device was booked in i was asked for a proof of purchase of a device which was purchased 4 years ago (bear in mind this was already replaced with another one). Again by far the most unprofessional service from a cellular brand. iStore Gateway Durban has all the relevant information regarding my issue.
