End of phone contract.

I am so annoyed over Vodacom contracts,

My husband took contract phones for both of us with different durations. When his ended they were trying to coerce him to upgrade by switching his phone network off and he fought it off until his phone was back on. Now in March my contract ended and all of a sudden sim cards can't be read by the phone, I went to a vodacom shop in Rustenburg mall and they said maybe it's the phone and didn't assist much, recently I took my phone for repairs and they said the phone was blocked/ switched off.

Why do you do that @Vodacom? I need my phone to be switched on, taking a contract with you guys is a big ****, never again!! My phone is still in good condition!!!!
