Grupo UNO operate a number of gas stations in Cost Rica.
For some weeks they have been running a promotion whereby you receive a sticker with gas purchases. Complete a card of stickers and you can receive a sports ball for a token price. (football, volleyball, basketball etc)
The only problem is that the balls don't exist. Having duly filled my card with my 7 year old daughter we went to get our ball.
When presented with the card, the attendant cheerfully announced that there are none. Not at that forecourt or any other in the entire counrty.
Has the offer expired... oh no, the advertisments were still all over the forecourt
The head office contact details were given as a scribbled phone number on a scrap of paper, which inevitably leads only to voicemail
Grupo Uno continue to run the promotion,despite having no goods to make good the promise, and according to the people in the forecourt, not intending to get further supplies.
It appears to me to be a very shortsighted promotion..... get extra sales for a few weeks and piss-off all your customers in the longer term
