Upgrading contract without clients permission

<p>Dear Sir/Madam</p> <p>This is the second time we receive a sms that says that my wife has upgraded</p> <p>'' Y'ello, you have been successfully upgraded. Your next upgrade date is now 13/07/2019. Kind Regards MTNSA"</p> <p>Some one phone here a couple of weeks ago and she told him she does not want to upgrade, she will do it when feels like it BUT since then we have to deal with this sms that keeps on coming</p> <p>I have phone customer care the 1st time, they said she was not upgraded, went to the shop and told me the same thing but now the second sms has arrived</p> <p>She just phoned customer care and they said that they upgraded her contract. SHE DID NOT GIVE PERMISSION.</p> <p><strong>HOW CAN YOU UPGRADE A CLIENT AFTER THEY SAID THEY DO NOT WANT TO.</strong></p> <p>She did not give the person permission to upgrade. How difficult is it to follow instruction?</p> <p>This is wasting my time</p> <p> </p> <p><strong>Please fix it or I will move my wife account to another network</strong></p> <p><strong>Francois Archer</strong></p>
