Bad service.

Upgrading my contract at iStore was the worst decision ever! I had a contract with Telkom and every ran so smooth. Had to upgrade, Telkom did not have the colours I wanted so I went to iStore. They cancelled the contract of the first phones (WITHOUT my consent nor communication), the agreement was that they debit on the 25th of every month, tell me why they either debit before or days after the date we had agreed on?? Now they have cancelled my insurance for the current phone that I’m using and again, WITHOUT consent! Yes it was a missed debit but why are they only debiting on the 29th when the agreement was the 25?? I call so that I can ask for a link that I can use to make the payment… no help on site!! 😫🚮.
