Telkom reFUNed

After double payment was made (one debit and one manual) I have been battling to get my refund of R2600 since 23.11.2018. First I was told to wait 4 working days from payment date until it would reflect on their side. Every day since 28.11.2018 I've called Telkom and everyday its a new excuse. From "I've logged a call for the refund to be process" to waiting a week later to being told that the refund can only be done 14 days after payment received. It just doesn't end!!!!
