Credit not received

<br> Account A*** - cellphone no. ***<br> <br> I went into MTN branch - Elridge Boksburg on the 12/6/2015 to purchase a 24 month MTN Choice (3GB@169 per month)<br> The sales person: Nathalien Botes asked me if I wanted an open line. I said no.<br> So when I received my invoice on the 7/8/2015 I was totally surprised to see the amount charged for the excess above 3GB.<br> I then phoned MTN Customer Care and was told they cannot help me. I must go back into the branch<br> I went in on the 11/8/2015 and spoke to Angelique Van Altena.<br> She logged a query : Req *** <br> Up until 27 August 2015 I have not heard anything from the Branch. I phoned the branch and was told that they are not prepared to<br> pass a credit. I must get hold of the sales person Nathalien and between her and I she must come up with a payment option to reimburse me in her personal capacity.<br> Up to date I have not heard anything from MTN or Nathalien.<br> I find this very unprofessional as this was not my mistake but one of MTN's employees. I have sent e-mails to complaintsmanagement with no reply. I have phoned the headoffice and e-mailed again with not reply.<br> To date the amount overcharged R1187.53 ex vat.<br>
