Full of lies and worst service ever!

Worst service ever..first vodacome increased my monthly fee from R450 o R599. They sent email to say if there's a problem, we must call. When I called they said there is nothing they can do because the R599nis their cheapest package. Then this year another service provider came into our area. At my initial rate. When I called to cancel with vodacom, now all of a sudden they called offer me a cheaper rate but they said it was fixed for a year and it began in October 2023. I also asked them to move my line and gave them a month notice for December to which I was told, there would be no charge. Then I received am email to say they uping my installment to R599 again in April which is way before the year is up so they are in breach of their agreement with me and they telling me if I cancel I am liable for penalties yet they the ones not honoring the agreement! Further more there is no record of my request to move the lines and they are now saying they will charge me for that as well. They lie repeatedly and I a honestly want nothing to do with them any more. I'm the one that has to spend ages trying to get through to them all the time only to have them lie to me anyways! The worst customer service I have ever experienced. The also promise to cal back but they never do!
