Online upgrades - Service

This is now the second time that I've tried to upgrade online, and I'm really not getting any joy out of this. I thought that this was suppose to be the quicket and easieg way to upgrade however it is the most difficult one. An agent by the name of Jeremy assisted me on Monday and promised that I'll be assisted, however here i am still trying to upgrade... its really such a pain to upgrade... some agents don't even know how to be professional not to mention the managers. Every one promised me a call back the only call ive received sincr last week was from Jeremy. Wow... All im asking is for assistance if u r unable to help me please do let me know so that i can take my money elsewhere. Instead of making empty promises to your customers. I believe i am not the only customer that is not happy with vodacoms service.
