Incorrect Billing

So once again I must revert to Hello Peter and Social media to try and get any kind of service from Vodacom! First, it was the absolute MESS they made with my upgrade in June, and now Vodacom won't stop charging me for TWO handsets! I was only supposed to pay for 2 handsets until the end of August, yet they still charge me for September and now for October. Plus I was also incorrectly charged for two line rentals for 2 months running – at least I got that money refunded to me.. but that is where their service stopped. I have called Vodacom customer call centre SO MANY times regarding this issue and they can do NOTHING but log a call and tell me it is with "Back Office". Why Back Office is so *********** is beyond me?? NOTHING gets resolved. All that needs to be done is to refund me and remove the second handset installment from my invoice – Can it be SO difficult?! I don't know what kind of mickey mouse business they are running but it obviously is not for the greater good of the customer. I regret being a Vodacom Customer – enough said…
