Requested Statement with no response

During the month of June I requested 500mb of data be loaded onto my account, after 10 phone calls over a period of almost 2 weeks I only received the data on the 1st of July with no-one being able to tell my why it has taken so long and also not confirming when I would receive it. I have requested my July Statement via Facebook inbox message, last week Thursday 09 July, the response was that the query had been sent to customer care. I have now had to phone your customer care again and ask for the statement, 7 days after my original request. This is truely unacceptable especially after the loading the data was such a mess!!!!
