bad service is okay according to CNA management

On the 14/07/2015 I came into the CNA store in Irene and was helped by the manager, I remember asking him if its okay if I place a back-order and if there will be in stock or if its to late to order these particular issues.He assured me i must just pay for the back orders and the products will be in store on the 28/07/2015 the particular items will be here for me to collect.I paid for the issues and waited till the 28/07/2015 before i came into the store again. The products was not there but they told me come next sunday.The come next sunday message i got for a month long untill i came into the store one day and demanded the manager find out excatly whats going on and if the supplier can deliver or not.The first time since the transaction in July phoned me but this must be cause the area manager was in the store that day althought the area manager walked only slowly by to listen what its about he tried to avoid talking to me maybe cause he also dont have an answer.He promised me the items will be in the store in two weeks time.I waited three weeks before I called him,only to find once again no items but the message try next week.Today 4 weeks since he made his promise no one call.
