Bad Service

I have a Telkom mobile contract for over 2 years and it was due for an upgrade from last year. I only upgraded recently and received my phone on 25/02/2019. As soon as I took out the sim from my old phone to the new phone, It had no service. When I log on my Vodacom Wi-fi, I can received Whatsup message but no call or sms'. I've been trying to get hold of someone via Chat via Agent but no one can help. I've been struggling since. I then received my monthly invoice with pro-rata charges for the month of March, for a service that I haven't even used, worst part is that some of the things on the package expires month-end e.g. minutes to other Telkom mobile and data. When I phoned the number 081180 it does not go through from any number including landline. I phoned 10210 requesting to be transferred to the mobile division, the consultant checked my package and advised that I should be receiving phone calls/sms. She requested that I should consider getting my sim swopped. Today 7/03/2019, I went to the Telkom Sauer street and explained my predicament, I couldn't be helped due to not having Proof of residence only my ID doc. I was upset that no one could advise me on time and provide good service. I was put from pillar to post without success. I am not willing to walk back to the branch during my lunch hour due to Telkom's network problems and failure to provide good customer service.
