Poor feedbck on query

I asked for a pin for a lost recharge voucher for 8ta bought 14/2/15. Spoke to M Mokoet and he said I must send email with voucher number He told me I would get a response within 72 hrs.. Sent email 15/2/15. No response till 19/2/15. Called again and spoke to Jessica Tumelo 19?2/15 and she also said I must send an email and it will be resolved in 72hrs. She sent me a case number 20/2/15. No response by 26/2 and I sent a follow up email. Still no follow up a week later and I sent another email. I received a call 12/3 to say that themoney was recharged on 6/3 but when I checked it was the recharge that I did. I sent another mail that the problem was not resolved and still no response. I have been bounced from pillar to post between Telkom and Checkers where I bought the voucher and no_one wanted to take responsibility as to who is supposed to resolve the matter. The amount of calls and emails is not worth the airtime I have bought but it is just the uncaring attitude towards the call centre staff.
