Ignores my request afterTHEY made the mistake

It did go well until they cut us off saying there was a problem with payment. We couldnt find a problem so we decided to cancel it and take it out on my name. It was on my husbands name. I emailed asking is there anything outstanding and if so to let us know so we can pay it up. They confirmed via email on the 15th of may that it has been cancelled and nothing is owed to them. By chance i went through my husbands statement yesterday and noticed they collected their R99 fee on the 27th of may. So after having emails explaining AGAIN what happened and that they need to refund us they simply send us a mail saying oh NOW it has been cancelled and we now still have showmax until the 17th of June!!!! We dont want that! we want our money back. Why would we want to pay double for showmax as I already have it on my name??? Are they sly or ***********??? And the number I called the lady back on just rings....Im now going to the bank to TRY get this money back as they dont want to give it back....I know its only R99 but if they do this every month???? You do the math....
