Cannot recharge or buy data now for more than 20

Hi<br> <br> It's dissapoiting to see such a known and trusted network not being able to assist me load ,check and fix what they did with my sim that now I cannot load airtime or buy data bundles.<br> <br> I have called the call centre more than 6 times and no one can assist ,which in those instances one staff member advices that she is putting a service request which only later I found out she didn't ,upon calling again I encountered an agent guy who was rude and sarcastic without being sympathetic since I was frustrated ,spoke to the team leader to report the bad service I encountered ,she promised she will sort it out and I will get a call of apology from the agent till today I haven't received that call.neverthe less the team leader helped with logging a service call that would be escalated to the technicians ,which it was done few days later I received an SMS that the problem has being sorted if it's not I should go to one of the vodacom shops ,which I did yesterday at Evaton Plaza I was told by one of the employee that they can't help because a technician at their shop doesn't work on Sunday and in all the vodacom shops .the service I am experiencing is unacceptable .im losing business
