Telkom ~ Credit on Old Account needs to transfer to New Account

I received an SMS from Telkom back in February 2018, regarding a Credit Balance on my old Account. It said to call Prudence on ********** 417 to arrange a Refund or Transfer funds to my new Account.

There is in fact an outstanding Amount brought forward on my "New" Account of +-R130

I have been trying on and off for 5 months now to contact this person, the phone just rings and no one ever picks up. Today, the number is dead...

Please can someone contact me regarding this amount?

Thank you
