Delayed Refund by telkom

I cancelled my Telkom line ***because was no longer happy with service. I was billed for the month after my notice period which i then queried but was told all was in order it would be refunded together with my deposit. Indicated date for refund was 1 October 2015. The refund together with my deposit hs not been paid into my account and when i try to call the call centre I am put on hold with message that Telkom is short staff because of ongoing industrial action. I dont understand the delay in the refund of money which was not supposed to be taken from me in the first place.<br>
