Bad Service ?

I recently took out a mtn contract which consists of a phone and a watch. A Samsung galaxy A32 5g with a Samsung galaxy watch active 2

My parcel was delivered to me last week and I have received the wrong watch (Samsung galaxy watch active). I have made numerous phone calls to mtn and they have given me different numbers to phone but no one answers. Mtn customer care says that they cannot help me as I have taken the contract out online and that is not their department.

The number I was given by 5 customer service agents either does not ring or I have to hold on and listen to the tunes playing for hours on end *** *** *** ***

I would just like the mistake to be rectified or for someone to explain to me why I have gotten the watch active 1 and not the watch active 2 (which is the one I app**** for and was told I was getting)
