South African law says that you have 5 (five) WORKING days (not including week ends) to cancel any timeshare or timeshare type agreement.
1). Always cancel in writing! Fax a copy to the marketing company, the developer and TISA and remember to keep the fax receipt.
2). Phone to make sure that they have received it (take the name of the person you speak to and record the time and date of your call).
3). Post a copy to the marketing company, the developer and TISA (make sre you send it by registered mail so that you have proof of postage).
4). Return any literature, sales pack or promotional items that you were given but remember to keep the copy of the contract that you signed. If you keep anything baring the contract they will find a way to deduct it from your deposit or any capital that you have paid.
I know that this seems to be extreme, but these people will stop at nothing to prevent you from getting our of your commitment to them.
You need not give any reason for your cancellation as it is your right to do so by law. The company has to refund any monies that you have paid (in terms of a deposit or capital amount) in full and are NOT allowed to deduct any administration costs. In your cancellation letter request the refund of any monies paid within 14 (fourteen) days and warn that any time after this will incur interest (your right too).
Do not be bullied or persuaded - if you have changed your mind it is your right and you are allowed to do so with the full protection of South African law.
