pathetic service and no feedback

I have returned a smart device back to you after having it for one day and not even activating the sim cards yet I have been billed 3 times already, your call centre contacts me and says that I will get feedback of why you guys billed me incorrectly and yet its been 6 days since I last heard from your *********** staff who don't know what they doing. who is going to pay for the pathetic services I am reciving for payments deducted for stuff I don't have, whos going to pay for bank charges for deductions taking place on dates I never agreed too ever. you guys have been my trusted and preferred provider but have really tarnished your reputation as a service provider, you guys are pathetic cause you are quick to collect money but have no recollection of whats happening. then I need to hold on when I try to call for ages because of probly all the complaints you guys received. ****ed, disappointed, hate Vodacom and want a resolution as soon as possible.
