Poor Customer Service by the store manager

I went to do an upgrade at Vodacom Festival Mall, after an upgrade my sim card only worked for about two to three days, after that it stopped working. I went back to the store and I was told the package I was upgraded to will ONLY work on a home router. The manager at the store named Fikile Khoza was so rude, bad attitude, didn't even bother to give me options and solutions, now my number is not working, I have to wait for the whole month without access to my number, she just told me " we will cancel your contract". She didn't even care whether Vodacom will be losing a customer or not. She has bad attitude, lacks customer service, I don't even know how she became a manager of the store. She didn't even bother to apologize, she dismissed me every opportunity she got, a whole manager 😡😠😠
