Delayed service for repair

I gave in my phone S7 on the 7th of August 2017 for a repair due to the battery swelling up. I was told it would take 5 to 10 working days. I have not received any feedback yet for the progress on my repair, when you use the online smartcare website to check progress all it tells me is my job number which I already know no other info is provided. They have not emailed or SMSed on the alternate number I have provided , when you do phone in to the branch ********** 7715 you hardly get through it's always on hold and when you do all the lady could tell me is that they are awaiting parts from overseas. I find this lack of interaction with the customer so appalling as we are left in the dark not knowing when the repair will be done. I have emailed off the website and the supervisor ********** . I have not received any feedback or acknowledgement of the email. I have also informed the consultant that in 2weeks I will be moving out of Jhb to Kimberley and need my phone before then. Your service delivery is shocking the interim music that is played for the customer for the call center needs to be changed it's definitely not world class service and absolutely not the service I dream off. My job number is ********** 007. Also I might add the repair is under warranty and it's a fault on Samsung parts due to its battery swelling up, it's not a repair for a cracked screen or water damage.
