Worst customer service

Network fault from 24 Dec. Visted 2 Vodacom shops, called in numerous times , logged numerous faults, made many customer complaints & it’s still not fixed? I had zero phone reception of any kind for a week & still only have e connection & calls dropped or unclear. I just don’t know how to get a meaningful response from anyone at Vodacom. You must always speak to someone else & escalationimg the problem achieves absolutely nothing. Due for an upgrade, so will swop service providers.
