No feedback even though I told it would take 72hrs

A while back I bought a recharge voucher to the amount of R50. I tried to load the airtime on numerous occasions but was not able to and as a result the recharge voucher was blocked. I let it rest for a few weeks then I called the Client services department for assistance. I gave them all the information that they required and I was promised that the issue would be resolved in 72 working hours. I'm sad to inform you that it's a month if not more since my incident has been logged and to this day they still haven't given me feedback or resolved the issue. My mobile number is *** the Ref No. of the incident is ***3. The call centre consultant who logged the incident is Shonese Ellie and her Supervisor/Manager is Kabelo Mbitse. I am extremely perturbed as I spend quite a large amount of money on recharge vouchers to be treated with such impunity. I know the two individuals I've mentioned only escalate to the relevant department but as such they were my first point of contact and point of reference. I'm fully aware and understand that it's the department to which the matter was escalated to that is not coming to the party.
