Cancellation of services from overseas - VODACOM !!!!!

Cancellation of services from overseas - VODACOM *****!!!!! - No email / contact us info to sort out queries. I've done everything to cancel my vodacom services when I started with my relocation overseas last year. I've cancelled my mobile number a month before I left (October 19), and the other services on my account was transferred to my ex-husband (November 19). I left South Africa end of November 19. Part of this services was 3 x modems ***, ***, ***) that I had for my children. Vodacom advised that only I can cancel it in Jan 2020, although all other services on my number were transferred. Since January 2020, I've send mails, gave my ex-husband & daughter a proxy letter and authorization to cancel on my behalf, as I am on USA cellphone service provided, and can't phone the 6 digits numbers as advised on the vodacom website for international queries. vodacom is dedecting R1510.00 per month from my account, every month... Nor my ex-husband or daughter, with full authorization letters from me, or all my hundred's of email were attended to or my cancellation solved. This is just unacceptable and a ********** behavior on their behalf. The more they ignore your request to cancel, the longer they can deduct the money from your account. Please cancel all your vodacom accounts before you relocate
