refused to block my sim

I lost my phone on Sunday morning. I then went to Vodacom in Dobsonville mall to block the sim as i had very important e-mails and messages that i did not want to land in the wrong hands. I had my driver's license at the time as it has the same id number as what is on my id document i did not see it as a problem as what was important at the time was just to block the sim. I also tried to get hold of the contact centre without any luck. Nonetheless, Mpho Mudziri who was very rude, unfriendly and kept using her phone to chat and make phone calls refused to help me. The manager at the time Shabnam insisted i drive 40km home to get my id. Went back to Dobsonville after an hour and all they wanted to do was to look at my id and proof of residence, no copies were made which really frustrated me. I've used my driver's license to do an upgrade from other branches without any hassles. Mpho told me that there are different rules for each branch but i am a VoDacom customer and the rules should apply across all the braches. I was also told that the insurance claim would be submitted on Sunday however was only sent through on monday. Please address this urgently to ensure a non repeat of this.
