POOR SERVICE VODACOM

Hello. Vodacom suspended/locked my accounts because someone I don't know asked them to suspend, what happened to security check do they ask the customer questions before they do such thing. My account payment is up to date and yet I cant use my cellphone, this is so annoying. I have 3 lines with Vodacom they unlocked my one line, the next day I realised they didn't unlock the other 2 lines I called them and asked them to unlock of which they refused and told me they need to follow procedures and report the case to their ***** department-how come the procedure was not followed when they decided to unlock my other line. its been 5 days now and nothing has happened not even a phone call to update me what happening. Poor Service!!
