Whatsapp Ticket Problems

Previously I have never experienced this problem but it has persisted over 10 days now. I am experiencing problems with the 1GB Whatsapp ticket I purchased. I recently used the My Vodacom app to purchase this Whatsapp Ticket but it has not worked. When I open Whatsapp the symbol and wording of 'connecting' continually runs and no messages can be received for sent.

I have no issues with Whatsapp using normal data, wifi or a wifi portal modem as I have tested out all these options. This is very annoying as nothing seems to be resolving this problem. I am wary to contact a customer care line as I have had bad and unhelpful experiences in the past.
