Bad service in general

Over the past 6 months my parents had a contract with Aida Rustenburg to look after their rental property and to pay over rent to them. They could never get it right to pay the correct amounts over on the promised dates stipulated in their contract. Numerous calls had to be made by my Dad and hardly ever was a call returned. Then as we decide to not renew the contract with them they allow the tenant 20 work days (BTW - they count Saturdays as a work day) to get out of the house which will be on the 10th of September. On numerous occasions it was explained that they should call if there is something important since my parents do not look at their e-mail every day but they did not deem the tenants moving out as an important issue I suppose? My folks only discovered yesterday that a e-mail with the notification was sent to them on the 19th! Aida did however phone my Dad this morning to complain about some problem with the geyser? Interesting how they found it easy to phone in this case. We are holding our breath because will they be able to at least take the final meter reading and work out the final monies if they could not get it right in 6 months time? Bad service in general!
