services keeps getting disconnected / barred

Vodacom disconnected my services on 7 August 2019, why? The call centre agent stated there is a problem with their network as my account is up to date! I was reconnected! I was disconnected again on 12 August 2019. I called the call centre again! Was told the same story, problem with their network! I was quite livid at this time as I have my retired folks on the contract, so that they may use the phone anytime esp emergencies etc. so she reconnects me but my 2nd number was still not connected for 2 days! That’s the number my retired Dad has!! I called them to enquire as to what the fault it. I was told to switch the phone off and on again! We did that and a pin was required. My Dad inserted the pin and the sim card locks! So I am angry at this stage and ask the agent what is going on! She says that I must insert the PUK. We told her there is no option on the phone to insert the PUK as the phone won’t allow up to go further and states SIM LOCKED! I was told we need to do a sim swop and I am liable for the costs! I was so frustrated as I am paying so much for the contract and Vodacom does not deliver the service they should! 2 days my Dad could not make or receive calls! All I get told is to get a sim swop!!! My Dad and I discussed that he will go to the Vodacom shop the next day and lay the phone on the table. He hears beeps and then the screen shows that he needs to input his pin again which he did and then it works! Are we going to be compensated for those lost days and for disconnecting and reconnecting me; disruptive services and waste of my time waiting for 20 minutes before an agent took my call on 12 August 2019. I called again today, 17 August with a query, held on for 17 minutes without assistance!!!! Vodacom used to be the BEST network but now….
