i store South Africa

after being placed on a waiting list for the iPhone 13 pro max at the Cresta Store i received an sms to collect my phone. went to collect phone on a new contract with Telkom when i got to the part of the application that ask to debit my account, i told by Japheth Pather the sale consultant that telkom's policy was you could do 3 months debit and change it to EFT monthly after 3 months, i said ok i need to see that in writing. He told me he needed to check with his manager Samantha Zulu, he came back to me and said the manger was checking on it, i then ask him to show me that in the contract since thats what i was signing, he looked and looked and looked and said its not in the contract, and then he went back and fourth to the manager with out a resolve. i ask him cant he or his manager give me a written statement saying that what he was telling me about the 3 month contract change was what i was agreeing to in the contract. After going back and forth with him and her i agreed to sign the contract i just wrote on the bottom of it that i was told by him and her that what they told me about the 3 month change to the contract was in fact in the contract. well they refused to sign. the manager then told him to put the contract through, well after that i was told that there was an error on the contract and it needed to be escalated. i spent 2 1/2 hours in this store being told a bunch of lies by this i store staff, it a shame that core has to have such dishonest people selling product that they lie about to customer. i am a very dissatisfied customer. My hope is that through this correspondence, someone from the management team will be able to resolve this horrible state of affairs .
