Call centre not answering since monday

HI

please note I have been calling Vodacom call centre 111 and 155 since Monday and I have held on twice for at least an hour and no one is answering I try at least every hour to call but no luck.

I bought a 1gig for my Samsung S4 and Vodacom only loaded 390MB . im now on out of bundle and its costing me a lot. please can someone tell me what is happening as im racking up the MB and its not my fault

thank you Ref is S3- 04C82-2V1T
