I Bought R200.00 vodacom airtime from my FNB banking app but my airtime is not reflecting m, I called FNB and I was given a merchant reference number: 665368 and I was referred to Vodacom to get the voucher number. I called Vodacom, my call was dropped two times and I managed to speak to Nolufefe who confirmed that the purchase is showing on her side but still pending, I requested to speak to the supervisor and told me that there is no supervisor ar the floor but she has escalated the query and provided me with the reference number:S-CSRISFI70 and promised that the supervisor will call me back. I called again, my call was dropped 3 times after the 4th call I was referred yo Contract section where I spoke to Lesego whose quested a screenshots from my banking app. After receiving the requested sreenshots ,Lesego called back to inform me that the airtime purchase is not received by Vodacom and he is unable to give me the recharge voucher, he then referred me to FNB. After a long hold while on conference call with FNB, the call got disconnected.
