Upgrade done without my consen

Firstly app**** for a upgrade for a device, bundle option, Samsung S21 & A5, delivery failed after 7 days, after few days are many calls, they said it was stollen and my personal data was exposed due to this event. Then i went to telkom I got the devices same day even cheaper.

Now my sim only contract has expired, I call them to cancel as it has been converted to month to month deal. Boom call center agents tells me that i have upgraded! I ask when? How? No answers. She says she will escalate issue, with 24-48hourse someone will call to resolve this. 1st of July new contract (that i never requested) is starting today 30 June. No one has called, I can not cancel expired contract, they decided to do an upgrade without my consent. Such pathetic service horrible to the core.
