Bad service from Vodacom cancellations.

Morning, Vodacom cancellations has gone very bad and l think it is a strategy to keep clients, this needs to be looked at by Ombudsman or relevant authorities. I called in and tried to cancel one of my contracts and spoke to a lady with an Indian accent. The phone cut, l called back and no answer. The next day l called in and spoke to a black lady, same thing happened. I called in after some time, spoke to another black lady and the exact same thing happened. I went to a store and was advised that cancellations are only conducted via a call. Now l am stuck and cant be donating money to Vodacom.
