MIGRATED ACC WITHOUT AUTH-LOST ALMOSTR1000 AIRTIME

Ms Naidoo spoke to my wife 12 Sept asking if we want to upgrade. I was on mthly Straight up 100Top Up. She said if we didn't upgrade we would lose the number? On 15 Sept we decided to upgrade to R249 pm deal on Straight up 100Top up with a J5 Samsung. I work away and had to sign for the handset delivery so I made it clear to her that delivery was to take place by 20 Sept or contract was to be cancelled. On 18th Sept 2 sms were received. <br> Once read:Thank you for your request to migrate, it will be effective on the date you specified. <br> The other read:your Straight up 100 TOP UP has been migrated to Straight Up 100 POSTPAID effective immediately, your new subscription is R110.00. <br> FIRSTLY MS NAIDOO you **** about me losing my number, SECONDLY At no time ever did I request a migration. <br> I then contacted Cell store Tygervalley who said they would fix it up. Krysia did the upgrade and then informed me that I had lost all of my airtime, nearly R1000 and that the migration request had been put through the week before. *** I only spoke to her on 15 Sept. On whose authority did she act. SORT THIS OUT NOW, refund my money, cancel the contract and put me back on monthly subscription
