Bad service from vodacom

Please assist as I have three vodacom contracts I've been trying to cancel the two contracts but I've been struggling as I've logged cancelation last year November 2023 but till to date it has not been cancelelled.. The Sim cards are not in use.. I've been asking time n time again for cancelation but nothing has been done!!!!! Please can you assist as I've stopped paying now it's in arrears.. But cancelation should if been processed last year... as this is pathetic service I've been a loyal customer but sadly the service is rock bottom pathetic even at the vodacom Newcastle mall store service is absolutely terrible...!!!

Please can someone call or email me with regards to this matter as I've tired of calling the call center and asking for the same thing which is still pending a simple cancelation???

Regards

Very unhappy vodacom customer
