Worst service provider

Its now been 5 weeks since my sim card hasn't signal & when I call CellC all they could say is that I should buy a new phone whereas my phone is less than a year old. When I put my vodacom sim card into my phone it works well. And again CellC doesn't want to cancel my month to month contract even though their ******* sim card is not working.

If there was a negative rating I was gonna give them a negative because they don't even deserve this 1🤬🤬
