Monthly Contribution set to MAX

Medihelp send the annual proof of income declaration in October 2014. I have requested proof of income from the employer and only received it on the 9th of January 2015 (Payslip for November and December 2014). So I phoned medihelp and asked if I can still send through the Proof of Income and the signed declaration so that the monthly contribution can be set according to the salary scale. The lade rep**** that I can still send through and they can amend the contribution. Now at the end of January, I find that the monthly contribution was send to the highest salary scale. When I phone to confirm, I get told that I submitted late and that it will only be set to my salary scale at the end of February 2015. So why can some consultant tell me that I can still submit and then they still bill me for the incorrect amount. I would like a manager to contact me regarding this. I have never had an issue before and now because I have received proof of income late from the employer and asked if all is still in order for proof of income declaration. Decide well you have submitted late, sorry for you. Not even seeing that I have tried to submit although it is late and consider my payment option.
