Makro not giving Sunny Chairs advertised

I ordered Sunny chairs for my son via the Makro (Pickup). Upon my arrival the product that they wanted to hand to me was not correct and not what I ordered. The first manager the attendant at the front desk called indicated that I should just take it and return it.

I indicated that I am not taking it as it is not the correct product.

The attendant once again returned and indicated that the product I ordered online was advertised incorrectly and unfortunately I can not receive the items I ordered as they are more expensive.

Makro if you advertised something it should be given to the customer that already paid for the item.

I left after an hour of the matter still not being resolved
