Vodacom the Grove bad service

I went in to vodacom the grove happy to be upgrading my contract on the 1st of march 2018, I asked for the package deal where you get the sony XA1 phone and a playstation PS4 , the sales consultant went to the store room and came back with the word that they do not have any XA1 or playstations instock ...she told me that she can order the deal for me and that she would give me a call as soon as the stock arived ,the deal would expire on the 7th of march and she told me that the deal would still be available because I ordered it before the deal expired,I agreed and left the store . a week of waiting patiently I decided to phone the Vodacom store only for them to tell me that the playstation arived but the Sony XA1 has not and that they would call me if the stock landed so I started waiting patiently again for another week with no one getting back to me. Yesterday 16th of March I called the store again to find out where my order was the consultant told me that th Sony XA1 was discontinued ,I then asked the consultant if I can choose another sony phone with the deal and she said yes .On the same day I went to the store and arived at 18:00. I was met at the door by a consultant and therefore explained to her what happened . she brought out the Sony XZ1 and I agreed to take the phone with the playstion PS4 , she then told me that she cant give the deal to me without the sony L1 which is a new deal where you get the PS4, XA1 and L1 as a package deal I said that this is fine and I would accept the deal . she went to the storeroom and came back telling me she does not have the L1 in stock . I told her that it is ridiculous and asked her why she does not have stock if you are promoting the deals .She told us that we should phone different vodacom stores to find out if they had stock ...we declined and told her that she should make the calls. as we were sitting there she phoned 3 different vodacom shops with none of them having any stock of the deal I accepted to make things worse while she was phoning other vodacom shops she was busy on her facebook . Another customer walked in and asked 2 ladies if he could buy airtime they both ignored him the customer raised his voice and said to them"is one of you going to help me" they still did not answer him ..one got up not saying a word and walked off ,the client asked again " excuse me should I follow you or what" finally the consultend answerd with a soft " yes" and that was it .Now I want know 1.Why was I not told that the phone was discontinued 2.If I hadn't phoned the store myself would they have called me? I believe the answer would be NO! 3.why are the consultants so arrogant and if I as a client get upset why do they give me bad attitude.
