ACCIDENTAL BLACKLIST OF MY CELL PHONE & NO REFUND!

my Samsung suddenly started having connection problems during June 2015. after about a week of struggle and 2 telephone calls to the Telkom call centre i was advised that nothing is wrong and my sim card is connected. I thought the problem was my phone cause the sim does not give that problem when in another phone. talked to samsung itself and was advised various times that i should take the phone in. I did so. had to pay R1700 for a main board that needed to be replaced. CASH. after twee weeks waiting period i got the phone back. the first day it was fine like always but the second day it was doing the same!!! called Samsung which advised me i should take the phone back again and PAY AGAIN!! after that phone call i read on the internet about the emergency call only and not registered on network problem. called Telkom mobile call centre. advised me my phone was indeed blacklisted ACCIDENTALLY because someone else wanted to do a blacklist and gave an incorrect digit and ended up being me!! lodged a claim. they said i will get a refund. few days after that some rude lady called. just asked if the phone is still blacklisted. said no. claim was for refund. she put the phone down...
