********* business practice

So I get a phone call from “Vodacom Business” (telephone number happens to be listed on my phone as spam) the lady informs me that I am “overspending” on my package which is a Ref premium + with unlimited sms and calls 10 gig of data, more than enough. She tells me that my spend was in excess of my contract and I inform her that it due to the fact that I transferred data to my son, then she acknowledged that she saw that! Then she advised that my other contract is not a good contract and I should migrate, she gives the incorrect spend amount and I confirm that it includes my handset installment, I currently pay R417 and she advised me that I can pay R527 on the migration contract and it will be the same as my current spend???? Did she have math at school??? Thus my spend will actually increase with almost R300!!! R500 package + handset???? How is that not an increase in the mo they spend??? That is how Vodacom gets clients to commit to higher packages while informing them that there will be no increase when they can see all the info on the system while talking to you!!!!!! Shockingly *********!!!!
