Very poor and arrogant service from Zahrah Almas

I am really frustrated and fed up with the service i have been receiving from Client Services Administrator by the name of Zahrah Almas , i have emailed you guys a thousands times as per tickets number - MWB ********** and MWB ********** . He or she is not willing to help and resolve my query, i have been asking for the correct billing of my account and he\she has been very arrogant where incorrect information was given to me, i need to the calculations and ask everytime where certain figures comes from, can someone working with coporates account and willing to help and resolve my query go though my billing and advise me on the correct amount due. I have been charged an amount of R371.37 and R218.53 for 1st May, why was i charged so much for one month while im on a R349 package with R219 discount?
