Telkom Terrible service from call center to Telkom store.

On the 15/05/2025 I upgraded my Telkom contract online; I then received my phone on the 19/05/2025 after receiving a call from the sales department to confirm my upgrade. I then tried to open the sim slot to start using my phone, but it did not want to pop open. I contacted the sales department immediately to advise that the devise is faulty, i was told to take it to the nearest Telkom shop for help. When i got to the shop I was dismissed like I stole the phone. I then contacted Telkom again and the lady who assisted said she logged a case for the phone to be collected. This all happened on the 19/05/2025 when the phone was delivered. From the 19/05/2025 the Telkom sim lost network I could not make calls. On Saturday the 24/05/2025 I then decided to contact Telkom because the devise was not collected, and my network was still off but the installment was deducted. I was sent from pillar to post calling different numbers to get assistance. I then decided that I want to cancel the contract and was told to contact the retention department. I called and was told that I will contacted to cancel the contract, I was also told that the collection request has been escalated, and the phone will be collected on 27/05/2025. The retention department called while I was at church on Sunday and I did respond to the email sent that they could contact me back but when they called again I was not available. Then Monday they did not call today the called when I was in a meeting at work they called 3 times at the same time and then sent an SMS that my case has been cancelled because I am not answering the phone. I then called to find out what is happening the lady that assisted was not even interested to hear my story, she told me to take the collections number down to follow up on when the phone will be collect, I refused and she hung up on me. My case number:***0 cell number in question: *** ,Mpho Mushiane. I am still waiting for someone to collect the phone and for assistance with cancelling the contract and I'm told my case number is cancelled. The service I received was terrible it's like I'm asking for free phone meanwhile I pay for this service just to be treated like trash. The network is still off all I need is for my network to come back on I will use prepaid and for the faulty device to be collected because they will start charging for this new contract and the phone is faulty.
