Bad Experience with Apple Applications, need your help

Hi, I’ve recently installed 3 Applications that offered a free trial of 7 days and then an hour later, the same day I installed them, I deinstalled them all, because I didn’t find them useful. A week after that day I recieved 3 e-mails, right after their free trials ended, that I have been charged with the monthly or yearly fees they have. I now want to contact my bank and ask to not give a permission to them anymore and make them unable to charge me again, but also I want my money back. Should I ask every one of them apps to give me my money back or you can help me take my money which I never agreed paying to them and I was lied very roughly about. Also, I ordered a new credit card, but I have to give the new informarion to the AppStore and then the wheel turns back on. Tell me, please, what is the order I have to follow now? These Apps are: “TapeACall Lite: Call Recorder”; “Call Recorder for iPhone - Rec“ and “Call Recorder - Record Phone Conversations”. Please help me! Why does Apple offer such problematic applications and have them in the AppStore? Don’t you have some kind of system that recognises them and takes them out of the business? It’s not fair for us - your customers.

Thank you in advance!

Best Regards, Martin
