UNACCEPTABLE SERVICE/ CUSTOMER ABUSE

I have a book to write here, however I only have 1098 characters left so hopefully I get a response. Galaxy S5 G900. IMEI: ***. Received at the Samsung Smartcare Centre for a cracked screen, 10/02/2016. Proof of purchase requested and forwarded. Called to follow up to be told that they had received info & the technician still had to check the phone,an sms would be sent when phone was ready, it was a screen warranty repair -Quote received liquid damage ? never mind the phone is used by my 14 year old daughter,we paid the R1539. on 9/03/2016. NO SMS. called centre - collect phone 17/03 Guess what - all her photos are gone !! back to the centre 18/3/2016. Only to be told that there was no memory card in the phone - SORRY ?? We only know that the sim card must be removed. Asked for the Manager ,Dorothy was useless-ASK FOR senior manager, Riaan in the toilet, wait 15 minutes. Riaan - a wiff of alcohol on his breath, said the memory cards are removed and given back to client. this never happened all we got was a receipt, he starts shaking and shouting that we have accused him of being a ***** HUH ?CCTV footage would be checked, we must come back - REALLY ? Call me Please.....
