Heartless service, 905

Worst assistance from my bank ever. I have canceled my subscription with my network provider and they have provided all the relevant emails even a picture of the canceled sim card. However still proceeded to take a unauthorized amount of R2051.00 out of my bank account. I have provided all the relevant to capitec as well as sat at the branch for 3hrs with the service provider confirming cancelation over the phone and sending the documents again and again. Capitec will not release my money. Them being my bank should be acting in my best interest, but are making me feel like I am asking them for there money. I am a single mom and you have taken my groceries money to feed my kids and are making me beg for you to dispute and refund my own hard earned money... from 8:30am till 18:30 last night I have begged and pleaded and cried at your branch and your heartless approach to wanting more information after receiving the relevant. I WANT MY MONEY!!! You as my bank should reverse my money and leave me to handle the service provider which is canceled and month to MONTH. STOP TREATING THIS AS IF IM ASKING FOR YOUR MONEY... GIVE ME MY MONEY BACK!!!!
