No feedback on broken bag

I have experienced terrible customer service from Mango. Over a month ago my bag was broken into at the airport on my trip from Johannesburg to Durban. I complained to Mango and was told that they would repair the broken bag. I handed the bag in and received a reference and was assured I would be kept updated on the status of the bag and that it would not take long to fix (the zip just needs to be replaced). It has been over a month with no feedback. I have emailed numerous times. I have messaged the Facebook page directly and gave them fair warning that if they didn't phone me / contact me, I would be writing a Hello Peter complaint. I was told I would be contacted but no one has done so yet. This is unacceptable. It surely doesn't take over a month to replace a zip, and even if it does, to not be given any feedback, ESPECIALLY WHEN REQUESTED REPEATEDLY, is horrible customer service. I am seriously reconsidering if I should remain a Mango client at all. I am going on holiday at the end of this week and need my bag. I have constantly asked to be given the courtesy of knowing what is happening with my bag which was broken into by airport staff, which in and of itself is unacceptable.

Please give me an update or else I will take this further. If I do not hear back by the end of today I will be posting on Facebook and Twitter and expect to receive another 1 star Hello Peter review.
