Mobile contract

On the 2nd of June, I called the telkom call centre,spike to the lady by the name of Ditoro Tsutsa. I needed to upgrade and whilst speaking to her I told her advise me about different phones I could take,she kept having PC issues and asked me to Google the spec of the phone I wanted, I therefore did my own research about a different phone I wanted and sent the phone she sold back, today is the 9th and I haven't heard from her, I've emailed Ditoro and she has blgiven me no feedback on the progress. Her service is pathetic once done with the sale they don't care about the customer. She needs to be more knowledgeable about the products so we as customers can make an informed decision instead of doing our own research. I would like feedback ASAP as telkom lacks communication skills.
