Please do your Job!!

I called and cancelled one of my contracts Mid December 2023. The gentleman explained that I will still be debited for it once more as it was not the beginning of December which I acknowledged. I was then debited twice after this, I called again and spoke with a lady who told me that the man did not cancel as he was supposed to and that she will do an immediate cancellation and my credit will be refunded in 48-72 business hours...this too was not done! I called last week and provided the case number along with what the lady said. The gentleman then said that they will review my recording and that they will then phone me but if that is what was said it must be honored.. The lady also did not put a full cancellation as I requested also, which can also be heard in the conversation. Well it has been a week and still no one has contacted me. I want the contract cancelled and my money back that was promised to me please.
