VODACOM AND THEIR RIDICULOUS POLICIES

I have been a customer of Vodacom for many years, my account escalating between R 4 000.00 and R 5 500.00 per month. Now all of a sudden after an upgrade I have a credit limit of R 2 500.00 on my account and my phones get soft locked every single day. Vodacom take their money by debit order every single month and I have not missed one payment on my account, now I am paying full price for all these contracts which for the past plus minus week I cannot use. This is unacceptable consumer behavior and I expect Vodacom to sort this out immediately, but you can never speak to a superior or the so called "back office". Some days I have to phone Vodacom up to 3 times to unlock my cell phones.
