Where is my data! Bad service to the bone!

I bought Mo'nice data for R24 for 2 gigs which i needed to use in 5 days. I bought this at quarter to 6 the evening on Saturday the 8th of December so my data would keep me till Thursday the 13th of December till quarter to 6 unless i used up my data before then. To my suprise i received an sms just about quarter to 1 saying my data has expired on Thursday morning. So i checked my previous purchases where i also bought the exact data for the exact price and saw that those to expired before time. So i phoned Telkom and spoke to a lady to whome i explained my whole situation too. She than confirmed that the data expires at 12 midnight on the fifth day. I told her that this does not make sense cause that would mean i get 2gigs of data that i need to use up within 4 days and a few hours and not 5 full days. So i asked her to get me a manager. Instead she transferred me to another agent. I than asked the second agent for the name and surname of the previous agent that assisted me but according to her their system was supposedly down. I then explained my situation to her as well and i asked her if she agrees with the previous agents respond. She said she couldnt say and needed to confirm. I was put on hold by Nikita from Durban who then came back and confirmed that the data do indeed expire on the fifth day at 12. So in order for me to get a full 5 days i would need to purchase my data at 12midnight on the first day. So i asked to speak to a manager since no where does Telkom advice its customers of this specific rules regarding mo'nice. I then asked he why it is that when i purchase data for a day it doesnt expire at 12 but works within a 24 hour cycle. She couldnt explain. I was put on hold for the rest of the call for longer than 30mins before i dropped the line. She did not come back to me once to confirm of i was alright and whether im still willing to wait. The entire phone call was longer then an hour. Her excuse at first was that the supervisor was busy on a call and i informed her that i would wait. She had an excuse for everything. Why did no one call me back since they did take my number on both occasions. Bad service. I work within a call centre environment so i know what im talking about. For a company like Telkom i have been utterly dissapointed. I want to be reimbursed for the data lost ? Where did you inform me that my data will expire at 12. And be aware this happened on a number of occasions. Give me my data back. Let me guess... this query will fall on deaf ears! My number is **********
