Complaint

So to actually begin what happened with my story with vodacom.....On the 27th of June I made a R500 payment to vodacom right...I was advised I can make the payment then on the last day of the month when my debit goes off it will reduce the bill of the payment I made on the 27th of june 2018...however on the last day of June a payment of R1148 was debited out of my banking account ....I called in the first week of July 2018 requesting a refund as my account should be in a credit cause the full payment of R1148 was still taken despite the R500 payment I made on the 27th of June 2018.....I spoke with over 5-8 different call center advisors who alone does not know how to speak to a customer regardless of the situation however I was advised Mr Oliver your refund has been sent to back office ...4days later I call up the next advisor says no u need to get proof that u made the payment number one I no longer have the receipt secondly is I went to the vodacom store in cavendish square Claremont to request the proof of payment I made of the 27th of June 2018 for R500 they told me they don’t have the records or cannot do a reprint of the receipt for me....I called in again to the call center I was told bluntly !!!!!u need proof we can’t help hence this is money on my account...then eventually I got a bank statement as proof sent it to an advisor and said Mr Oliver it’s all sorted I must wait 7workings days I said okay....I called in 4days later guess what ? The advisor never sent my proof off no one could track this conversation I had apparently with the advisor then some team leader tells me I should of never sent it to her....think about vodacom you guys are s company right so if one of your staff members says il send the proof of payment off for u il trust there word however this team leader made as if this girl was wrong but then again everybody who works for represents vodacom as one and not as an individual.....remember if I owed you money you would of chased me and block my services if I never made payment right ? So why when I was chasing money that was rightfully mine not knowing my situation all I was then told il apply onto your next bill that’s not the issue the issue is the principal behind it...till right now 08/08/2018 I never got my refund and I never paid my bill for this up until I get feedback
