Must buy more points to use existing points

When it came time to renew membership and pay for the next year's points allocation, I wrote a reply to the e-mailed invoice ( [Email Removed] ) to inform them that a) I wished to retire from this club as our circumstances had changed, and b) to please use another e-mail address for future communications, which I supp****. Nothing happened and another e-mailed invoice duly arrived at the old address. Having no other address for them but as above, I again sent them the same e-mail. That resulted in a phone call from Cape Town, a certain Ms Kumbu, I think her name was, who advised we had to pay for another batch of points before we could use the ones we had already paid for. I argued this point but she was adamant. I explained that we were now not in a position to want/need or be able to use more points but wanted to use some of the \old"points for a friend. That was a No No. We have 59 points that were paid for last year and now cannot use them unless we pay~ R13 000 to receive another batch of new points. Why? We have since repeatedly received invoices (to old address) with interest added onto the amount payable."""
