Bad assistance with unblocking my phone

Phone was accidentally blocked/blacklisted last week. Lost all connection on Monday evening and have been struggling to activate it again since. Have called into Telkom over 10 times and they have advised that the phone has be activated and is no longer blacklisted, however it is still not working. I cannot be without a cellphone and this is URGENT. I am extremely upset with Telkom, most of their agents have no clue what they are doing and have wasted my time repeatedly this week. I am waiting for a technician to get back to me and am afraid of how long this is going to take once again. Endless problems with Telkom. Case number: ***1
