Right to Fair and Honest Dealing

Tracker finance department once again added additional amount to my billing. They seem to ignore correcting their error and sending me incorrect billing each time I request for an update in my billing. Note that I do not have or given any contractual agreement for charging this additional amount. Tracker cannot just add any additional amount without agreement. This has happened previously adding additional amount to my account and after several months was corrected and reimbursed. This is happening again.

It seems like they always trying to **** me.
