One of the business practices that drive me mad is when somebody comes out with their own package, and then sends you an invoice for your payment without you ever having agreed to take the product in the first place. This causes confusion in an office, and before you know it, people are running around trying to pay the item and you have never ever expressed interest in the first place. The latest invoice I had in this regard is from a company called sadcyellowpages.net who want me to pay R400,00 a month for an entry in the SADC directories. Quite frankly I think directories are yesterday’s business anyway, but sending me an invoice without having agreed on same, is sure to put me off ever using the product.
