Inconvenience caused

I just had a sickening stinking bad servoce from vodacom. I took a contract last year in july, been using that number since then till 1st of january when they locked it. Tried calling vodacom call center various times.. Then finaly went to vodavom shop where i was told the number doesnt belong to me but to a company but surprisingly the invoice was sent to me the whole time not to that company. So finaly l was told to make a sim swap and get another number and l am the one responsible for paying. This has so much annoyed me that l even wish to cancel that contract. My problem with vodacom is, noone want to take responsibility for that inconvenience caused, noone want to apologise, life goes on, noone cares, that number ********** 536 that they had mistakenly gave to me as they claim, now l have to go Everywhere where lve registered that number to change it to the new number, iam very dissapointed with vodacom, i hav been wth them since 2011,why is it tat noone takes responsibility at vodacom, noone attends to complaints, what business are they running that at the end of the day they care less abt customer care bt all they want is your money
