Vodacom is *****ing our data and airtime

Vodacom is *****ing our airtime and data. I bought a Just for you data bundle from the Vodacom app using my airtime. This morning I saw that my data bundle was not allocated but my airtime was deducted. I phoned customer call centre and firstly I was not served in my own language and secondly my issue was not resolved. The consultant checked my account and according to her the data bundle was allocated, however I did not even received a sms confirming my bundle purchase. In my opinion it was allocated on their side but not send on my account. I am considering to cancel my contract from Vodacom. Very unsatisfied with the service.
