FNB Connect- Worse service EVER!

I Order a product online from them on Monday 10 Feb. Received an sms on Tuesday to say that the product is now with the courier company and will be delivered in 2-3 business day. Wednesday (10:51AM) between FNB & the Courier phones me and states that the product is out of stock and it was their mistake that they never notified me of this and their fault it was still showing as available online. They also said that they are not receiving anymore stock of that product from their suppliers. We should cancel the order and place a new order on a different product. I then asked when would this be delivered, they told me that it would depend if they had the product in stock and how long it takes for the courier company to collect it. I then kept calling in to tell them that this was unacceptable and i want my order delivered by no later than Friday close of Business. I have been on the phone numerous times as well as corresponding via email about, no1 can tell me what is going on or they say they will escalate my matter and yet NO1 has done this! I have even in contact with Karabo, *** as well as the supervisor from Digital Planet (FNB) Whitney. Karabo has told me he has escalated it to his line manager and this manager escalated it to Thabang Mapango, however not 1 of them have been communicating with each other. My husband then received an email from Karabo saying that " So all its done you should be expecting your delivery tomorow" his exact words, when i can DP and chat with Whitney, they know nothing of it and it will take 3-5 working days for delivery. it is a constant struggle. This is really unacceptable on any level, this is not the type of service to be expected from FNB. This is also not the 1st time i am struggling with FNB! Get properly trained and qualified people behind your call centre staff or I will be moving banks. I have truly had enough of the pathetic service that FNB has to offer- FNB how can we help you, more like FNB how can we waste your time and money!
