Non communicative Vodacom company

From day 1 with my data contract with Vodacom it was fraught with miscommunication, incorrect information given, blocking my number because I made to many phonecalls to try sort out what was happening, they promise to get back to you am waiting 4 days for a promised phone call. The contract has been cancelled as they couldn't activate the sim card. They kept f me 3 days from working as am self employed and live in Tsitsikamma, have invoiced them and cannot get through to their legal dept. Have tried to contact them through all social media to get a response and nothing forth coming. Twice bitten I twenty years with a contract so obviously they have not improved the methods and they catch their customers out. I cannot recommend this company at all. They blocked my prepaid no 5 years ago and now I cannot contact them as my number is on the system as a spam call. How can someone work with a company like this
