Bad Service

Terrible service I have placed an order with Ackermans online and have chosen the collect express option due to an urgency of my parcel but when I track my order it shows the parcel has been In dispatch since the 2nd of January with no further movement, and it shows my parcel will only arrive the 12th of January mind you on the delivery options it shows 3-5 days now i did not count weekends and public holidays. So I am worried because when I call the customer service line there is no answer! This is utterly disappointing because there are things in there my children need asap! If there js anyone who could assist me from courierit i would really appreciate it.
