Not going the extra mile

On the 14 June wanting to purchase a Jacket to the value of R1300 as it was my birthday the 19.One of the ladies was checking on the system and saw that there store has got one but it was a set a side.She than check again and told me that somerset got 2 unitso and tygervalley 3 but she will order it right now and than I can come pick it up during the week.On the 18,19 we phone but there was no feedback.Yesterday again I phoned only than to discover that the units is sold out as that stock which the stores had was all set a sides.I feel that this service was poor an unacceptable.it's not my problem that the liaison officer was off sick ,the store manager had to follow up and see to it there's a second in charge.there is so many staff in that store but they don't go the extra mile.I am really very disappointed coz maybe if they followed up maybe than I wouldn't have felt this way
