Horrific service really I am in shock

Sunday I went to your Tygervally store to get Nappies and baby whipes on the promotion you had. Someone at customer service tried to help me but later the evening I saw that 1 box of baby whipes was missing from my order. So i reached out to your customer care and even tried to call you people. I tried to cancel the order via desktop to reprocess it correctly (which I could not do). Monday I spoke to Brandon and Gershwin and they assisted me, my last call was with Gershwin and he assured me that it has been taken care of and that I do no have to do anything from my side. Tuesday, Lindsay calls and said Tygervally dont have stock and I said that why I purchased online because your store dont have stock (this is not my problem) later that day she called and I asked so the order is not being delivered she said no there is no one to collect the stock from another branch. Gershwin also called with regards to the order and I told him Lindsay could have informed me that my order would not be delivered today instead I waited, Gershwin fully agreed it was unprofessional on her side. Moments ago today I received my order 1 box baby whipes short, please tell me why I went through all this effort to correct a mistake that most likey your staff made on my app just so it wasnt delivered?? absolutely pathetic service, I am disgusted really I am fix this immediately and to top that off I paid and book a slot for delivery and that was a pathetic fail. Your level of service is horrific
