Vodacom continues to disappoint

Following my last review, Vodacom indicated that a consultant would reach out to me to resolve my issue, which they haven't. My line is locked again at the typing of this complaint, having just called Vodacom Customer care to have it unlocked on Saturday. It's getting ridiculous now, the least, seriously the absolute least they could do is tell me why this keeps happening. I deserve to get the service I'm paying for, if not I should be allowed to cancel the contract.
