SAMSUNG S7 REPAIRS

A couple of month ago my Samsung s7 edge fell and my screen broke. I later went to Samsung store Somerset Mall in Cape Town to enquire how much it would cost for me to fix this crack, they told me about the ADH warranty my phone still qualified for so it the damage would be don't for me for free. On the 27th of January (which was on a Saturday)I then took my phone in for repairs, the technician in store told me it would take about 3 to 4 working days for the screen to be fixed which mean day 1 would start on the 29th of January and I would possibly get my phone by the 2nd of Feb. I was also told that I would be contacted with the regards to the progress of the phone but to date I have received no contact from Samsung. Every time I call in and ask to speak to the repairs guy in store I am always told s/he is busy and my contact details will be taken down but I never receive any call, Its been over a month now and I don't have a phone.

I am very unhappy about the companys service, its pathetic
