Poor Service from PME Attorneys in Ballito

Helene from PME Attorneys in Ballito KZN requested a valuation report from me for a 2.2 ha property that was being sold by one of there clients. I sent the report with my invoice for the cost to do the valuation to Helene. after a few weeks of not receiving payment for the valuation report i called PME Office to be informed by Helene that i must ask the seller to pay me for the valuation i sent her. I informed Helene that the seller did not request the valuation from me and that she requested the valuation from me and she needs to pay me and not the seller of the property. To date no payment received. I even left a few messages with the owner Vincent of PME concerning this matter to date he has not bothered to reply to my messages I even tried calling Vincent concerning this matter but he does not answer my calls either.
