Poor communication from Homewood

Hi there, I ordered a custom build coffee table from Homewood furniture in Sandton (Kramerville), I paid almost 50 % of the total cost of the coffee table as a deposit for them to start with the manufacturing of the coffee table, I also bought a plasma stand from them at a price of R17500 prior to ordering the coffee table, before they started the manufacturing process of the coffee table they sended me a drawing of the design and dimensions of the coffee table to my email address , I then confirmed with them that I'm happy with the design and they started with the manufacturing process, after the manufacturing was completed one of their salespersons phoned me and said that they are finished with the coffee table and that I need to pay the outstanding amount, then only after one week of paying them the coffee table will be at their display shop in Kramerville for collection, I told the salesperson that I sold my bakkie and will have to get hold of someone with a a bakkie to assist me in the collection of the coffee table, I told him that I will pay the outstanding money to them a week before I collect the coffee table and he agreed to it. The salesperson then communicated with me on email while I was on holiday but I didn't receive his mails because he entered the mail address wrongly, he even admitted to sending it to the wrong email address, The salesperson then communicated to me by watsapp after noticing that I don't reply on my mails and said that I need to pay the outstanding money for the coffee table because their manufacturing warehouse is going to charge me for storage of the coffee table which is R4000, I then told the salesperson that he must convince them to cancel the storage money because I didn't get my mails which he sended to a wrong email, he then also agreed that I was not at wrong and after a while notified me that their manufacturing store doesn't want to cancel the storage fees, I told the salesperson that he will have to communicate to the manufacturing store and tell them that he was at fault by notifying me on a wrong email, still they don't wanna drop the storage fees,I did pay for the coffee table in full but still don't wanna cancel the storage fees, I spended R41500 at their store for the coffee table and TV stand and this is the service I get for a mistake from their side.They never told me that I will be charged for storage, and if I was notified on the correct email address I wouldn't have been in this situation.
