poor service

I am ver disappointed because I lodged a complaint againt telkom sometime last week and received a feedback message wherein I was promised that someone will call me.To date no one called or attempted to call me instead I received a statement where I am billed the sum of R406, for 2.5 Gb and R505.00, the question is does that address my problem, no it does not at all.My query is, your consultatnt told me that I am going to receive the same package I was on and now I am being charged extra which is something that I did not agree upon with Telkom. I guess I have to beg now that please call me so I can explajn to you what I want qnd dont add things to my accountwhivh we did not agree on as that constitutes breach of agreement
