ENQUIRY REFERENCE NUMBER : ***

I am writing this email to express my concern regarding an overbilling issue with account 19090. I was told that I owe R 500 and now it is R 1800 which I don't understand the amount to this point because my payment plan is the debit order . Around March the 13th I called to inquire about my contract coming to an end , then I was told that my contract is coming to an end around October which was fine by me . I my surprise i received the call from one of the call agent to inform me that my contract is coming to an end end of this month which was March the call i received was on the 14th March around 14:45 and i was like i been asking about the issues since the beginning of the month and now final someone is telling me the good new .So my come to an agreement for the technician to come an install the new system and i said let's wait for month end which was great and the technician came on the date set . On the 6th April I called again and I was told that i cancel my subscription which that's why I was charged the amount of 500 and something and my channel was open.
