Bad service

I visited the Builders warehouse in Port Elizabeth to purchase laminates and other related material. I already had a quote with, which I advised Mthetho to change the colour scheme from Cherry to Rust Maple. To m surprise when they went to load the laminates in my vehicle, I took note that they had brought the Cherry laminates and not as per my request. This meant the new quote was not modified. I immediately brought this to Sharon's attention and she requested Mthetho to amend the quote. It was already close to closing time and I had wasted about 15 minutes of my time, trying to have this rectified with the cashiers for a refund. The refund was processed successfully and I was charged accordingly for the Rust Maple laminates. However, the store did not have other items i had purchased such as, the underlay, skirtings and the door strips. I was advised timeously about the out of stock situation. However, upon settling the sale for the correct laminates, Sharon came back to me and advised that the manager has offered to deliver the laminates free of charge. This was obviously due to the fact that it was already past closing time. I anyway agreed to the delivery service but I further made a request that the laminates are not delivered the following day but rather all the material is delivered together once everything has been received by the store. I further advised Sharon to provide me with a quote for the stock which is not available and explained that I will make an EFT deposit in order to make sure that the items are delivered together. Sharron promised to call me before the delivery was made, to confirm details. To my surprise, the driver phoned me today and told me that he is on his way to my address for a delivery. Nobody contacted me regarding this, which meant my request as a customer was ignored. When I phoned Sharon she advised that the manager made a promise to deliver today and that he refused to deliver once all items are received. (As previously agreed on discussion). Not only was it their error in the first place, they are not rectifying it by meeting their end of the deal. I fathom to understand that a customer's request can be easily ignored like this, and I find this type of service very appalling. It was a great inconvenience go all the way to the store to be incorrectly charged and given poor service. The people at the warehouse are not even trying to rectify their error and leaving the customer satisfied. To my understanding, you go out of your way to keep the customer happy, which was not what i received.
