Vodacom running a ****

Vodacom is surely running a **** with our money. I closed a contract with them in September 2020 and to my shock they were still debiting my account. I followed up to be refunded for a good 3 months and each time I am told that my query is in progress and I will be refunded in 14 days. I am still waiting even today. To make matters worse, it seems like robots handle their queries because each time I get a different report not related to a response they last gave me. They also assign random date as to when the query was logged which is ********** but covers them in this **** of theirs. Their Twitter page has blatantly ignored my complaints for months also, also on their page they insist it is the right channel to complain. I am really disgusted by the service.
