Non disclosure and misleading advertising

We recently purchased a property through Lencar Properties and was assisted by Tony. The levies were advertised to be R 1300,00. At no stage during the purchasing of the property were we informed what the levies would encompass. To our surprise the levies were double the price. Emails for Tony and Ricky have proven worthless as they did not address any of our concerns when replying. Instead, we were told that they hope that "things will work out". Also, no levies invoice for the previous owner was shown to us to make an informed decision. This was deliberately withheld from us to close the sale. We would not have purchased the property if they could have been honest with us concerning the levies and if there was full disclosure. Where are we supposed to get the additional moneys from every month ???
