Disgusting Service - CTM Alberton

On the 17th August we called CTM Alberton and spoke to a sales person by the name of Sharon , we enquired about stock on a certain tile, she advised us that they had stock and we arranged with her that we would collect the very same day. On arrival to collect, Sharon took close to 45 mins to look for the stock, only to tell us that there was no physical stock at the Alberton branch. We understandably asked her to please source it for us from another branch and to advise us when we can collect. After not hearing from her for basically a week and a half we called back on the 29th of August, following up on the status of our order, we were told she wasn't at work and Thabiso the manager said he would investigate and place an order for us. He promised he would phone us back the next day. This, however, did not happen, therefore, on the 30th we followed up with Thabiso again and he confirmed that an order had been placed and that we would probably receive the stock on Wednesday the 4th of September, which we again understandably agreed to. Wednesday came and gone and we did not hear any further feedback from him. On Thursday the 5th of September, we called again to follow up with him and he informally and casually told us he wrote our number down on a loose piece of paper from his diary and he had lost it. He then advised that he was going to verify if the stock had arrived and he would call us back. After a good hour, we received a phone call from him advising us that "We're going to fight with him" as he still had to place an order as the original order had not been placed. I find it completely disgusting that customers get treated in this manner and honestly disappointed at the lack of respect. Both Thabiso and Sharon had multiple opportunities to make things right and they failed terribly to do so. I am extremely dissatisfied in the manner that our order was handled and in the detrimental delay it has caused to my construction plans.
