CellC - Worst customer service rendered

Firstly my order was in correct and I was wanting a certain tablet and they selected another tablet that I didn’t want and it was only picked up early this week just before dispatch. ALL through this week o have asked and made sure my parcel arrives on Friday and alas their courier can only do it on the 29th of December. There was no follow up or apologies and I have to pay R2500 to get this tablet to my residence.
