Vodacom unreliable and dishonest

This is a follow up on last week's complaint. Vodacom does not put in a lot of effort trying to solve any complaints, even as serious as *****. Vodacom managed to call me back on Saturday night 19:00, but because of Vodacom's "work from home" policy, the line quality was so bad that I could hardly hear the consultant. The consultant decided to send me an email to apologize for the inconvenience. A matter as serious as breach of contract and *****, you don't fix with informal email with a short apology. I do not wish to continue my business relationship with Vodacom any further and need my contacts cancelled and penalty fees transferred to Vodacom. Again Vodacom has proven to be unreliable and dishonest.
