Vodacom up to s**t

My boyfriend took out a contract a year ago. This month he was like 4 days late with the payment and they switched his phone off. The following monday he went to pay the outstanding fee. That was 2 weeks ago!!!! His phone is still off he tried phoning vodacom everyday from Tuesday this week where the phone ends up being put down after 20minutes of holding. No call back no answer nothing. He went into the vodacom store itself and they keep telling him they don’t know why his phone is still off. This is unacceptable. They are quick to turn off the phone but take they f***ing sweet time turning it on. When our contract are done we are cancelling it and moving to another provider.
