Bull**** service from Telkom

Went to upgrade an existing contract. Firstly the consultants have no knowledge and very slow, they are not helpful They don't have stock of what they advertise and cannot give you a date when stock will be received My phone was due for an upgrade I was told no stock of the phone then was asked to go to a Istore as they will do an application. I was declined due to me having 5 contracts. I store advised its been referred to credit bureau.My contracts are paid up to date every month I'm not taking a new contract it's existing that needs to be upgraded. Went back to Telkom they advised me new system it has to go to credit bureau Why are these clauses and conditions not told to a customer I don't think it's fair on a customer that pays every month without fail to go through such drama I have from other customers the bad service u provide never believed it until this happened to me
