"combine and ship" delays my order

i'm not happy about takealot's "combine and ship" shipping, when i shop at takealot, i gathered 3 different items and paid together, two of them was marked next day delivery, but after i paid, takealot system shows that i am going to receive the parcel after two weeks, it's very disappointing, can't it be deliver individually?so i can receive my items as promised date. and they don't give you a contact number to compalin and reschedule my shipping date. please if any viewer can advice? or takelot will reply me with solutions?thanks
