Flexi Club not keeping to their offer made

We have had a Flexi Club account for many years. Last year one of their consultants visited us in Secunda and offered the following:<br> Sell our time share to Flex Club in exchange for points<br> Our existing points would be combined with our new points in a new Flexi Club account with a very favorable minimum levy for life.<br> We accepted the offer.<br> Flexiclub has not kept its side of the deal. They now send us two invoices for two accounts.<br> I cannot pay the levy until they resolve the issue.<br> They will not reply to my emails and just continue to send invoices and now threaten with legal action.<br> I am loosing my opportunities to holidays due to them not sorting out the issue.<br> Please help<br>
