Poor Sevice in responding and addressing quiries

Remax (Heleen maritz) was managing my house that I rented out. In terms of the agreement once the tenants have moved out the agency need to do the inspection and identify the things that needs to be fixed and also ensure that the electricity bill is paid by the tenant. The tenants have moved out on the 1st of April 2015. I had to make several calls and send emails that were ignored for some time before they could finally do the inspection, I also did my own checks and taken pictures and forwarded them to compare it with their inspection in order to fix the things that needs to be fixed by the outgoing tenant. They did not respond on my emails nor return my calls every time I call I get promised to be called later and nothing happens. On the 8th April I forwarded the electricity bill that is due for payment on the 15th of April and followed up with several phone calls. To date I have not received any response regarding the payment of this bill. I have actually experienced poor service in my dealing with Remax, dealing with Remax it often leaves you with the feeling as if they are just getting the 10% payment for your rental but actually they have other priorities
