Pathetic service

On the 19th of May 2022 I visited Telkom Shop at Centurion (Shop 320A) to add a SIM card on my existing package of data. I wanted to add an existing Telkom number that I had. I was given a new SIM card with a different number now I'm sitting with 3 different numbers. The staff is ***********. On the 23rd May 2022 I phoned the shop there was no answer. Got hold of the Telkom call center I was told to visit the shop, I requested a contract cancellation fee quotation to my surprise the amount is above R8000 for a device that I didn't get.
