Very Bad Customer Service

I am really ****ed right now, I lost my phone on the 21May and I blacklisted it same day cause somebody stole it inside the shop luckily I found it the next day.I called customer care and I was told that I must go to the branch with my certified ID,Affidavit and a box and it will take 2-48 working days,To my suprise the guy in the branch told me that it will take 7 working days to be unblacklisted.On the 30th I did a follow up and the lady from customer service told me that the guy who was assisting me in the branch just sent documents and did not request for my phone to be unblacklisted.She then said she will send a request of which it will take about 3 working days,on Wednesday I did another follow up,and the lady told me that they have a backlog but they are busy with my phone which she will send a request that will take about 2 hours.I waited until in the morning still nothing,unfortunately I did not take the names of all this other agents who were assisting me.I call today to find out why is my phone still blacklisted after all this follow up,I was assisted by this rude lady by the name Lungile who was telling me that I must not teach her how to do her job,she is very RUDE shame.she told me that I must go back to the branch after I have waited so long.I really dont know what to do,I just want my phone to operate cause this is an inconvinience for me.
