Telkom customer care less about it's customers.

Telekom does not take it's customers serious. From last month I've been asking them refund my uncle's airtime that they have mistakenly recharged it to a wrong number. He was struggling to recharge so I helped him to contact customer care, that's where the problem started. We spoke to the 1st consultant by the name of Happy Ngcisa, after a day we phoned again and spoke to Nthato Nkosi. I inboxed them on FB, it's now 2 weeks nothing has been done. I really don't understand what is wrong with them, they take people for granted.
