Bad service

I was contacted Yesterday by Karen about the rent that I paid this month. There was a short payment and she threatened me with debt control, however, the rent goes of via debit order, so they did not do their work and before they even got their ducks in a row they send emails and they start phoning. And they were the ones who failed to adjust the debit order. And they also have a R700 contract fee that I must pay for the renewal. I would gladly have paid the R700 if they actually did their work and made the changes to the debit order. That is R700 just thrown into the water now. Please in the future do your homework before threatening your clients.
