Still waiting SN***

I don't make a habit of complaining but I feel left in dark.

I booked in my phone early December for a warranty screen repair.(Samsung the grove Pretoria)

I was told it would take 2 weeks maximum, after 2 weeks nothing was received then later an SMS was received saying the is delay, I understood because it was the festive season and you communicated, ever since then everything just went quiet I call almost every week now to be told the same thing (they still waiting for parts) .every time I call am told it will come on the Friday of that week I called in every time, I then called 29 January 2018 and asked for a manager to assist , the manager told me he will check with the stocks department and let me know the next day, I received no call 30 January 2018, So I then called today 31 January 2018, I spoke to a lady who told me again they waiting for parts and does not know when they will arrive and that I just have to wait. I've been waiting 2 months now , you told me 2 weeks.

Can this please be resolved urgently.
