Vodacom' blatantly refusing to help close a ********** account.

Vodacom's ******** conduct continues! I have lost count over how many times I have complained about the same issue to Vodacom. They have clearly showed that they are not interested or willing to resolve this issue of a ********** account. I have emailed the requested documents to two different addresses and only got nothing but SILENCE! I have contacted their legal department, who promised to send an sms link and never did! In desperation, I contacted their social media team and it came to nothing, as they want me to authenticate myself against a ********** account, ***???!! I was referred to the nearest Vodacom shop, who told me there's nothing they can do and suggested that I go to Vodaworld for help, 50 Kms away from my house!!!! I am beyond livid!!!!!
