No detailed billing on fibre data usage

<p>I have a 100GB data package with MTN Fibre. For some unkown reason, my data does not last for more than 10 days. This has now happened for three months in a row and MTN tell me that they cannot provide me with a URL report yet on where my data usage has gone. They can only give me a usage report that shows that at a certain time I used so much data- they cannot tell me what that data was actually used for. Surely this goes against the CPA? I should be entitled to see exactly what I am being billed for otherwise how am I able to ensure that I am not being billed for something I did not use?</p>
