Amazon

I am so sick and tired if this prime video by Amazon. I just use the 2 weeks free to see what movies they have.. It's a waste of time. Now they have my account details. Though I canceled it they still try to deduct money from my account. There is no way I can e mail them or use there so called app. It shows that it is canceled but why still try to take money. It's costing me R3 for every time they try to take money... I am almost R100 in red... This must stop and I have now idea where to get it in there thick heads to stop the bleddy thing...
