Pretor Estate

I am very disappointed with the customer service received from Pretor Home Rentals. I have a 6 months rentals lease with them and I have paid my rent in advance for the duration of a lease. I requested them to refund me a portion of the paid amount and I will pay my November and December rent when it is due because I have an emergency at the moment. Wilma Groenewald who is supposedly the account manager (with 0 s**** to deal with customers) informed me that Pretor cannot do that an when I asked for a reason she could not provide with a solid reason and all I got was some lame excuse of my credit score being low. I think the way in which this is handled is disappointing more than the refusal to refund me.
