You are just the worst ever

I had to down grade my 5G -from R999 to the R699 Package -the person I spoke to last month -told me no problem , on Sunday I got an e mail that I successfully migrated , I could also see the speed were down , but on Monday -they debited R999 of my account , when I try to sort this out , I am being told one story after the other , I bought my decoder , and from day one , had to pay in advance for the data I used , now this person is telling me , I am now paying for last month -although “ the migration “ was successful -when I insisted I want her to cancel everything , and give my money back , she cut the call -Pathetic !!!!
