Bad service

After receiving a call from the Vodacom CEO complaints desk, saying they would credit me one month device cost after the device had been in for almost six weeks and then getting to the shop after she told me the device was ready for collection and finding that it had been back at the store fora whole week without them contacting me. Consultant just blamed the computer system for not sending me an automated message. Once again "SWAK" Vodacom. Bad service
