Vodacom Failing to Assist with Sim Swop

Vodacom, why give a don't care attitude to your loyal client. I've been your client on one number for more than 20years & you cant assist with the sim swop for I lost my phone & that I did not recharged in the last 18 days after switching from contract to pre-paid. for god's sake, how do you expect me to recharge while still have more R150 airtime on my sim card???, I drove all way to your head office ailed to assist me . how do expect my contacts to reach me ???, I've been out of contact for 5 days now & expect my issue to be resolve......(sic)
