Bad customer service

Good day

I wrote a review a while ago regarding Vodacom and I was contacted and I was assured that my issue would be resolved. I gave back the voucher I received as it was collected by Ram and still my issue wasn’t resolved and I called Vodacom and I was advised than I need to pay a cancellation fee.I was told my issue would be resolved as the consultant selling me the deal was at fault and I was assured that my contract would be cancelled Vodacom I am starting to regret taking out contracts with you.
