Vodacom Onlines ridiculous contact centre

I am truly appalled by the service of the Vodacom online service contact centre, I called in to do an enquiry on an account today at 12:44 and spoke to a consultant by the name of Thandiswa, I asked to speak to a supervisor as previous experience due to the same query have been failed to be resolved for over 2 months, I was advised I was going to be put through to the supervisor and waited on the line for almost 15 minutes after which I was rerouted to the telephonic survey signaling the cancellation of my call, the behavior of the staff and reluctance to assist with our queries are extremely appalling considering that we are valued clients for over 8 years.

I want a supervisor to call me as soon as possible as I am now not afraid to get my lawyers involved in the situation!
