No follow up on a repair after 8 weeks.

I purchased a Sony Experia Z2 and for the first time i decided to test the under water feature and just like the many reviews I've seen online the phone stopped working. I sent it in for repairs with Telkom 8 weeks ago and haven't received one update regarding this since and when i went into store i was told twice by different agents that it takes 3 weeks maximum for a repair to be done. my bills are sent on time every month yet they cant have the decency to phone me to let me know whats going on or to replace my phone as the technician in store advised me water damage with a Sony Experia Z2 cannot be repaired, it has to be replaced. Pathetic customer service and when going in store all they do is send an email and this was the response i got back from the Device Life Cycle Management department- <br> <br> \Hi
