Vodacom is the pitts

On the 24th I had an upgrade done at Vodacom in promenade. The service was excellent and I got exactly what I went for. Two weeks later a get a call and some voice recording tells me that there will be a soft block on my line because my bill exceeded the limit allocated to my account. I call Vodacom on the 3rd of April and all the consultants tells me is "we apologize for the inconvenience caused" absolutely no solution except for the fact that I have to call in everyday to have the block removed (baring in mind they take 10-15 minutes to eventually answer the call). And my query will be resolved in 10 days. Last night I take a chance yet again as I have 2 contracts with them and its still not unblocked. The consultant that assisted me the advises me that the data/airtime/SMS bundles that I purchased prior to my line being cut will not be refunded. I then ask to speak to a supervisor who was extremely helpful. He advised me that if I pay the excess of R300. 00 my line will be reopened. I was very grateful for the service I received, paid the R300 and ended my call. I restarted my device and low and behold... It works... Fast forward 24hrs later and my line is blocked again. And email gets send to say that ONCE Again my service has been suspended. So... I am currently out of options. I've got airtime and data that will just disappear and not be refunded so Vodacom... What the he'll do you expect me to do?
