Worst service and *********** staff of VODACOM

I was trying to earn vodabucks but their system did not allocate to me on 3 different occasions. I contact the help desk via the app. Went through the authentication process for MY account and was told I didn't give correct answers. I asked where I need to correct or ask another question because there is different dates etc for certain things. Everything we do has security and with good reason. I applaude the security but to be told they cannot help me without giving me direction or even 1 chance to correct my answer is unacceptable. My whole query is about why Vodacom is not giving me my vodabucks when I earn them and not asking for account info, or change details or anything that would affect my account, I was asking WHY VODACIM WAS NOT GIVING ME WHAT US DUE TO ME BY FOLLOWING THEIR RULES TO EARN VODABUCKS. She cut me off and ended the conversation. I WAS LEFT HANGING. I don't see the reason to stay loyal to Vodacom firstly because they have empty promises and secondly because of their staff who supposed to show empathy and assist within reason and security. I hate Vodacom at present because this is not the first time I have been rudely dealt with because of their *********** staff and I say this because of their don't care attitude in branches and contact centre's.
