Disgusting service while ***** has been committed on my account

I have noticed a debit order go off my bank account which was incorrect on 29 March 2018. I then went into a vodacom store to query the debit order to which i was informed that ***** was committed on my account. I logged a complaint with customer care on 31 March 2018 to which i was told someone would contact me within 4 days. I followed up the query on 5 April as i never got any feedback since my complaint was logged and i was told by a customer care agent that someone would contact me on 10 April 2018, but if no one contacted me I should call ********** . I received NO phone call on 10 April 2018 to which i decided to call ********** on 11 April 2018 and a very rude gentleman by the name John answered which was NOT helpful whatsoever and cut the call. I then tried calling again few hours later and i had to call back more then 4 times until the same rude gentleman John finally answered again very rudely with NO respect and asked me what do i want, i then told him i am following up on ***** that was committed on my account , he then listened to my story and told me he would call me back in 5 minutes. I received NO phone call back and so i called back after 1 hour finding out what has happened and why did he not return my call, he then put me on hold for about 10 minutes and then a gentleman named Oupa answered who informed me he would work on my account and call me back on 12 April 2018 at 8:00am, it is now 10:00am and i have received NO phone call. This is disgusting service knowing that ***** has been committed on my account and I as the owner was NOT informed about it and money has incorrectly been deducted from my account, I have to keep on calling people at vodacom to find out what is going on and so I must waste my airtime (as the number ********** is NOT a free call) calling people who give me false promises that they will call back and never do.
