SAMSUNG J5 - SCREEN REPLACEMENT - NO RESPONSE FROM SAMSUNG

I handed in a Samsung phone for screen replacement at Samsung Century City on 7 December 2017. On the 19th of December (eventually) they came back with a quote, which I then paid and sent proof of payment of R1140.00. Up to today, the 25th of January 2018, I have not been able to get an answer on the progress of the phone by either telephonic contact or e-mail. My e-mails are not answered and the ********** 151 phone number just rings. When I eventually got hold of Samsung head office today and asked them how to go about to get a response out of their company, I was transferred THREE TIMES to different people and then CUT OFF! I rest my case. Such a big company and such PATHETIC service. Please get Samsung to respond to this complaint. The Job Number is ********** 753.
