Quick to take money, and then cancelled my order.

Telkom, you are very quick to take my money from my account after m y mobile application, then you just cancel my order, due to no stock (not even informing me, I had to keep phoning you!), and now, I am struggling to get my money back! Every time I phone, (if you are so lucky to get a call answered), you send me from pillar to post, with no answer! I will be cancelling all my internet and other connections with you, You are out!
