Forever out of stock

I app**** online at Telkom's website for an iPad Pro contract. First I was phoned, pre-approved and then informed there is no stock for the device I am applying for, my name will be put on a list and they will phone me as soon as there is stock. A week passed and I phoned to follow up on the order. When the agent entered my ID, there was no record on the system that I app****, she suggested hat I apply again online, so I did. The same thing, they phoned me the next day, pre-approved and again no stock, name on a list, they will phone me back. A week later, still no feedback, I app**** again, next day they phoned me....now they have stock. I was approved, order was given through. I received an sms I was pre-approved and an initial amount will go off my bank account within 3 days. The next day the payment went off. The day after that I received an sms that I have been approved and they are working on my order. Two days later I phone Telkom since I haven't received any sms or feedback since the sms. The agent gave me an order number and he checked on their system.....no stock again. He informed me that I will receive an sms as soon as there is stock and the device has been dispatched. About an hour later I received an sms that my parcel can be tracked on Courier It's Website and the product will be delivered within 3-5 days. It's been a week and I haven't received anything. I went onto Telkom's website and tracked the order....the status: "Checking Stock in our warehouse" with a smiley face. Phoned Telkom again.....no, there is still no stock. But I have received and sms for delivery!!!??? It's been a month that I've been struggling to get an order, when I finally got an order number, they don't have stock, again, but I a payment has already been taken off of my bank account. This is totally unacceptable and very unprofessional. I will be cancelling the order today, and if any payment goes off of my bank account again, I will simply just go to the bank and let them reject it. I haven't received the product, so why must I pay for it again. I will never make use of Telkom again.
