Don't use Telkom Mobile

Telkom is absolutely useless, I mistakenly bought R1000 last week Monday the 27th of August I then called into the call center the lady advised me that I refund could be done,I think called back on Wednesday the 29th of August and I got told that they are busy with my case, i do a follow up call this morning and then i am told my case has been closed and they cannot refund me however I was not notified once, I am now trying to get rid of the airtime by selling it but they have a limit on transferring airtime, they are absolutely useless and can't help.
