huawei 12SE has no Network (both sim trays 1 and 2)

Took contract phone Huawei 12SE in August from Telkom Rivonia Village. Phone has been giving issues with network and i called the store consultant that assisted me she advised i swap sim cards in the tray and i did ( sim 1 Telkom sim2 Mtn) they both switch of network at the same time. i called her she told me she does not know what to do since its after 7 days. on the October 17 I took the Phone back to the store and Neo promised to book it for repairs, she promised to email me the repairs slip. on friday i texts her asking for the slip she said their repair system is down, asked to please ask the Telkom Woodmead to assist to book it she confirmed also there the system is down. because all this didn't make sense to me I went to my nearest Telkom at Wonderpark mall PTA to ask if it is possible for 2 stores not to have access to the App, she told them the real problem is her password she forgot it but she **** to me saying its the system. fast forward= i called last week for an update she said she is off she will check the following day and call me, she didnt call i had to call her on Wednesday she told me the Quote has been sent to them that i need to pay R850 for SSS Cell repairs to fix the network problem and she told me my phone is out of warranty mind you its only a month and half. later she called said her boss promised to escalate that cause its still on warranty, asked her why did she say it was out of warranty she said its 1st time she deals with such kind of issue, i requested she asked her boss to add me on the escalation I wanna see the communication but it was never done. today 5 Nov again i asked her for feedback she said she will log in and let me. if Telkom is unable to assist me with this network issue can they please terminate my contract cause I'm paying for something that i don't have. i will paying for this phone for the next 22 months and already its giving serious issues, I miss important calls due to this network problem. their contact no: ***
