Lies and appalling customer service

Last month I went away on business. I needed data and went to the Vodacom website to purchase.An option was presented to add it to my account and I selected that for convenience. I repeated this process several times during my trip. I also went out of bundle for a stage (without warning from Vodacom), although that is not the issue in question here. My phone was suddenly soft-locked, crippling my business. I called the Vodacom call-center and was promised that it would be resolved in 6hrs.There was no change a day later and i called again, only to be promised a 1hr wait until it would be resolved.After no change the next day, i called again and was bounced around between 15 people in different departments - all unable to assist, but assuring me the next person would. Each time I needed to answer security questions. After wasting hours of my time, I was finally told to go in-store. I did this and without any security checks, my phone was unlocked on the spot. I also asked to have my credit limit increased as this was apparently the problem. My phone worked for 2 weeks, and now today - it is locked again. Called the call-center and when the agent tried to redirect me I simply gave up
