Account settled but harassed daily by Vodacom

Hi \Voda****\", <br> <br> I do not appreciate you harassing me for monies already paid to you on 01 March 2016 (bank statement sent to you)!!!!!<br> <br> As per your notification dated 17 February 2106 , and follow on discussions with your call centre staff thereafter, you debited my account on 01 March 2016 for the full capital amount owing of R695.00.<br> <br> Your lack of administrative excellence and customer service is causing me to have to reject up to 8 calls daily from an automated voice message service. I have also tried to no avail to have the call centre agents that I eventually get to speak to check with your accounts department, but they insist on me sending a proof of payment. Unfortunately, as VODACOM DEBITED MY ACCOUNT, I do not have a proof of payment but only my statement as proof that you got your money at the beginning of March already and should have already converted this account to prepaid as per my instruction at beginning February!!! <br> <br> Kindly reverse the service charge billed to my account at end March and convert this account to prepaid WITH IMMEDIATE EFFECT!! I want a personal email and apology from your Customer Operations Executive."
