VODACOM! The world's biggest ******

I had a contract with vodacom since 2011 and last year I had fell on hard times and they demanded I pay a fee to keep number. After that I was not under any contract because I was not receiving any data or airtime with them and this week they completely deleted my number from the network without any prior warning and for no valid reason. Went to a branch and spoke to a call center who basically told me "sorry not sorry" but I need to pay another exorbitant amount or else my number will be permanently deleted in Two days! Highly disappointed in this network that I supported for many years!
