Pathetic service from Vodacom -To black list phoe

My sister try to black list a phone with Vodacom. A consultant Sinethemba **** to her that the phone has been black listed. She called again they refuse demand a sim card that was inserted on the phone. She told them there was no sim card. They wanted a sim card number that was normally inserted in that phone. She gave them my sim card. Still refuse to black list. We cant remember old numbers that we dont have anymore. Phone was bought in 2010. We use that phone if our phone are faulty. It was used by my mother who passed on. <br> <br> My sister gave them my cell number because we use to insert my sim. They told us that IME number cannot be picked. Insurance company still have the IME number and insurance is being paid <br> <br> Customer service Didi the supervisor was so rude to me. She even gave me wrong contacts for Rica. She gave me contact details for faulty public phone. They demanded me to call them still couldn't get help.<br> <br> Insurance asked to ask them to send a letter that they can not pick up the IME number. Still they refuse. We are being send from pillar to post. Another consultant told me i should go to Vodacom we went the again no help. Pathetic service from Vodacom customer service
