Bad service from wonderboom junction store

My contract ended in November 2020, i called in December for cancelation since I was not aware that I should call for cancelation, i was told that it has been canceled, January debit order went off, I called again in January I was told it has been canceled. I received data and minutes on the 1st of February also on my app it shows that i will be debited again in February. I went to a vodacom store on the 2nd of February around 5pm in wonderboom junction in Pretoria to enquire i was assisted by a very rude male consultant who told me that i am asking him silly questions after asking him how long does it take for vodacom to cancel a contracts, he added by saying how will he know since he was not the one assisting me on the phone he ended up standing up and telling me that he's done talking to me. Very bad service from wonderboom store. I am so disappointed about all this.
