Vodacom Dissapointment

Terrible terrible terrible, guys stay away, my son has app**** online last year for a two phone iphone deal, they said delivery would ve within 5 days, after three weeks he cancelled the order. Vodacom went and had him listed in itc for a R200 cancellation fee....he only discovered that yesterday when he decided to give them another chance and went into the store .....how can they demand a cancellation fee when they didnt honor their initial agreement
