In my account I have two lines with each their own plans.

I have changed the plan for one of my line (ending with the last two digits:  3934) and the plan was changed successfully and the rebate of an additional $5 was applied since I have set up automatic payments.

A little while after, I changed the plan for my other line (last two digits ending by:  26) but the monthly payment charge and the additional $5 rebate for setting up an automatic payment did not take place in the billing section even though it mentions that the new plan I have chosen is indicated under "this is your plan" from the self-serve section.  

It has now already been over 10 days since I made the change for a new plan for this line therefore I don't believe this is the reason why I don't see the change of the new rate in the billing section along with the $5 rebate applied when setting up automatic payments). 

P.S.:  in the "your plan" from the self-serve section it indicates $34 per month and indicates an additional $5 rebate will be applied if I set up automatic payment which I have already done but in the billing is is $38

Can you please help in correcting this situation. 

Thank you in advance.
