Bill seems incorrect - Call center ***********

Good Day, <br> <br> I am having an issue with my bill. The amount seems incorrect and seems like I have been double charged for the same period. <br> <br> I have contacted your account department which could not explain to me why the bill reflects like this and then put me through to the sales department which could not understand why I ended up there. <br> <br> your dispute functionality on your website does not work as everytime I try log a dispute it does not reflect. <br> <br> Please contact me urgently so I can have this sorted.
