Telkom deliver and sell a phone, with delays and impossible to get in to phone for setting

Husain from Telkom phoned me from ********** 110 offer me a special on a Huawei phone model Y3 with two simcards, and made promises to me that have not been kept. The phone gets delivered and immediately I get a phone call asking me if I have received it because they want to activate the sim cards. This is a contract phone with one sim to be contract and a prepaid top up number. I n the box is two pre-paid sims with no indication which one is the contract number or sim. Then the Simcard is not activated within 24 hours and on enquirer I get an answer it coulk take up to 72 hours when it is not over a weekend. Will they charge me pro-rata for this month when they activated the sim or whenever I am able to use it, and I cant open the phone to get into settings and when I googled I see it is a general problem and there is costs involved in opening it, which i refused to pay and I want again confirmation that both sim cards can be ported, and by me at my house, and some one must phone me or send me a detailed example how to unlock this phone
