Incorrect Billing and a don't care attitude from their staff

I've been querying my account with Zelri Properties since October 2017, and every month since they have taken over our building I keep getting contradicting statements.

From statements reflecting amounts owing to R12000, my rent is not even R12000.

Every week at least twice a week I spend R30.00 in airtime calling them trying to get hold of Mila who is supposed to be handling our buildings accounts.

I can't even get hold of their Credit Control manager who for some odd reason is always in a meeting.

Ive been contacting their office since November 2017 is someone going to compensate me for my airtime waisted?

The service i'm receiving from this company is putrid,

When I eventually got hold of Mila in January she says to me I cant sit on the phone and call every one of you people...

Who the hell is you people?

Pathetic no sense of customer service at all, outright rude and disrespectful. you would think that if they have time to send out of letters of demand they could spend 5 minutes to try and get an account sorted out.
