No words to describe the worst service i received from their consultant

I always paid my account upfront and i last did the same i paid my account upfront and i still got an sms and calls that i still owe, i went and paid the full amount i was told i owe of R 7 199,95 and asked them to close my account after I actually made an upfront payment a month ago,

And after making that full payment I still got an sms saying i owe, i called in and i spoke to a gentleman who explained that he can see that i have been paying my account with no issues and he will get my account closed I don’t have to pay anything. Today am still getting sms’s that i owe, and when i call in they are unable to explain the issues with my account and the first lady i spoke to was very rude and nog willing to help, i asked her to put me through to her supervisor and she just put me on hold for almost 10minutes.

This company is claiming unnecessary money from clients and regardless how you pay your account they still going to ask for more, unless they only do this to black people, why are they always overcharging us?.

I had the worst service from alot of companies but this one takes the cup.
