Bad Service!!!!!!!!!!

I am saddened to be writing my very 1st review about a service provider my entire family has trusted for over 20 years. Yesterday my dad received a call from an unknown number and the caller claimed his from Vodacom customer services and wanted to confirm if my dad has requested a sim swap. Upon hearing that the conversation was not going anywhere due to my dad not understanding, I took the phone and the "consultant" immediately dropped the call. He called back twice and specifically wanted to speak to dad and I explained that he is 70 years old and does not understand English but he never requested any sim swap he has never lost his or blocked his phone. "Consultant" dropped the call in my ear and called again using another number and again refused to speak to me and said they will block my dads number. after sending 2 sms with the Vodacom customer care number my dad is unable to make nor receive any calls on his number. Today i tried calling the customer care number with my phone since dads phone cannot make calls, reached that automated machine "Thob" that could not assist and directed me to a store. I currently work from home and do not have time to be driving to the branch with dad to sort this out and its frustrating as well for him as he does not understand what is going on. Im utterly disgusted with the service thus far and I need to speak to someone asap to sort this out. Ms P. Dlalisa- ***Mr J. B Dlalisa- ***(not working) ***
