Billing query

Good Day. I logged a complaint last month about Vodacom having locked my phone for 5 days. I was assisted by Lesley Abels who more than made up for the downfall. He also advised me that my bill was roughly R550 and he would ensure that the bill gets discounted. I received an sms on 4 February to say that a credit request was completed and will take 24 hours to reflect. Thereafter I received another sms saying that a credit note for R291.46 has been processed. When I logged into my Vodacom account, this amount does not reflect. It shows R591. I tried calling the call centre twice and I was advised that Lesley cannot take phone calls and they will mail him and ask him to call me. That was on Wednesday already and he has not called me and I have no other way to contact him to ask him to fix this. Please can Lesley rectify this problem and revert back urgently. Thank you.
