holding on the line with no reply

A Pick Pay insert leaflet came out dated valid from the 12-24 December with lace dresses from R350 ad lace tops from R189. seeing that the add says selected stores only i called the head office to get more information on the add published i made the call 10 times struggling to get through to the department where i can get more information, instead of getting this information i was kept on the line for very long with people picking up the phone and doesn't say a word i got very frustrated and agitated what service is this and from pick and pay head office after all! i need urgent response on this bad service!
