Johannes Mavuso, a clients service manager at Gold for Life, said Tsetseoa purchased a Mandela set in 2014 in terms of an agreement of sale.

"It's not correct that he invested with our company. Gold for Life is in the business of selling coins/medallions, does not have investors and does not give investment advice," Mavuso said.

He said the clients simply purchased medallions at the going purchasing price. He said they also had no control over the market price and the agreement gives no representations as to what the coins will be worth over a period.

Mavuso added that although Gold for Life attempts to act as a market maker in respect of coins which it sells, their ability to trade exchange these coins at a later date will be determined by the specific market conditions prevailing at the time of the proposed trade exchange.

He said this also included, but is not limited, to supply and demand, gold price and exchange rate. Investing in gold is a long term commitment.

"Tsetseoa is also not committed to selling the coin/medallions through us."

Responding to complaints which appear on Hellopeter.com, Nadia Rampersad - the head of credit control at Gold for Life said they have had tens of thousands of satisfied clients over many years.

"There are unfortunately always a few dissatisfied clients, most of whose complaints are not justified," Rampersad said. She said they were in the business of selling coins.

"People regard gold coins as an investment. However, the complainant seems to believe he can cash them in with us which was, of course, never part of the sale nor our agreement to purchase," Rampersad said.

"...it is our policy, as in any business, not to allow clients to cancel agreements or refund the purchase price after sales are made."

Rampersad, however, could not explain why Peters was an exception.
