Very bad service Vodacom

My selfone was stollen and they say i havent paid my account and for that they cant help me at all !! But monday i have paid more than a R100 more on my account as what the vodacom person that helped me said i must pay. Now i cant get my selfone blacklisted and or even just get a new sim card so that i can so long be mobile because of my busniss that people fone me and i need to phone them as well. VERY VERY BAD SERVICE FROM VODACOM AFTER I AM OVER 20 YEARS A CUSTOMER OF THERES. But it seems to me i need to move on and away from them as well . my new no i got from Telkom *** with in 25 min even with a new selfone already been set up from them . Excellent service !!!!
