Disgusting service, what do people get paid for? Is it only about sales

I am totally disgusted in service of Vodacom, I have been trying from Saturday till now to blacklist a cellphone that was ******. I visited a store today, the manager was really helpful but staff was not willing to assist. The lady did not greet, just noded her head for me to come to her, then said wait for the other lady, whom was at the counter on her cell with a personal call. I then waited, she did even ask me last 5 nos. Dialed, after all the troule i been through to get the last 5 nos dialed. I asked her if she can assist to blacklist phone, rep**** i must contact 082135 which i ha ve done from Saturday up to now, All i get is a stupid chatbot that says it cannot recognise the cellno as its not vodacom. They are not willing to asdist. Cansome assist to blacklist this phone plse!!!
