*********** staff. dnt give sufficient information

I took out a contract with the help of Telkom rep at iStore Menlyn. The lady who assisted me told me to contact the call centre and set a limit on the contract so that I don't end up paying more than the initial R199 of the contract agreement. I did that on the 25/05/2015 and spoke to Sindiswa who confirmed I do not need to set any limit as it is already set on 500mb. on 25/06/2015 a debit order of R 370.32 went through on my account, no.1 is the incorrect date and no.2 the incorrect amount. called in again and spoke to Sinovuyo Nobanda who not only had attitude and put me on hold for more than 10mins without getting back to me. I requested the d/o to go off on the 20th not 25th. Then she tells me about pro rated something which was never explained to me before I even took this contract. This is money that wasn't budgeted for and taken on an incorrect date. I am waiting for manager Nkosikhona Msomi to contact me and explain. I want my refund as I was never told of this.
