Vodacom does not cater for Indians anymore

After 27 years of loyal support as a Red VIP customer to Vodacom,they now decided to block my line due to a petty amount outstanding of R300.The ironic part of this is there were times before that I was late with R5000 but my line was never blocked.Mo notification was sent to me of this areas amount, no This is the first time I’ve been treated this way.I’ve tried to explain my query to various different team leaders but they all have the same arrogant unreasonable way of speaking to me which clearly indicates to me that Indians have no right to raise such queries.
