Nintendo switch false advertising

Very bad experience with the service received from Vodacom customer service, online upgrade and store. I requested a Nintendo switch from my local vodacom store, on the 18 of March 2018 and today the 9 of May 2018 I'm still waiting on stock, what I couldn't understand that vodacom advertise this product since December and all of a sudden they don't have stock, but in the month of April they had a deal with a cell phone and the Nintendo switch. The deal I requested from the store was the swith with the mini wifi router and 5gigs day and 5 gigs night for 399 for 36months. I demand answers regarding me calling multiple times to stores and online to asisst but nothing is done.
