Disappointing service and cancellation rejection

First of all i would like to start off by saying the service at the canal walk branch is so disappointing. As i stood waiting my turn I heard numerous clients come in and have no idea where to queue and when they ask for assistance they get brushed off. <br> I cancelled my mobile data contract the end of February in order to upgrade to ADSL uncapped. I received an automated cancellation notification and got billed for this data contract the end of February. I went into the store querying this charge and was informed that the contract only gets charged the end of month and therefore that was the final payment for the mobile contract (which made sense). I then got billed for the same data contract the end of March and once again went into the store to query this. The mobile data assistant informed me that my cancellation was rejected??!! how can my cancellation be rejected when i am upgrading to another Telkom product which is more suited to my needs??! and at no point was i informed of this \rejected cancellation"this cancellation procedure has now taken two months and is still not resolved!"""
