NON EXISTENT XA1 ULTRA

The phone was advertised and MTN has been advertising it for more than 3 months but no supply as yet??

Cant believe I have been abused as a brand loyal customer to wait for almost two months with hope of getting my phone inthe next week. MTN says they are not getting anything from Sony but they keep on advertising it. Called Sony and was advised to wait till end of August? Is this workable??
