7 Days and no feedback

I sent Nerasha Ramdhani confirmation of the tracking number of the collection of the cellphone and sim card on the 11th February 2016 and requested feedback as to when this will be dealt with. <br> <br> She advised in the telephonic conversation on the 10th February that it will take +- 7 to 21 days to have a new phone and sim sent out to me.<br> <br> However I have requested for feedback as it has been 7 days and I still have had no feedback as to what is happening with my complaint.<br> <br> Is this what MRPmobile call customer service, I have been in customer service for more than 21 years and if my customer received the service I have received I would not have a job.
