********** transaction

I have a router contract with Telkom mobile with 99 pm subscription and in April they deducted 729 from my bank account when I enquired with them in store I was told that I took 2 cellphone contracts in March and I disputed that they them logged a Cas for me which they later informed me that it's resolved.and I reversed the 729. This month I received a statement which informs me that 630 will be deducted on the 30th June and the statement now show that the 2 contract are of a router I am being sent from pillar to post with no solution.
