MBD enjoy ignoring customers

So MBD spend every day harassing me with daily smses, forcing me to lay a few complaints before they stop. On the 10th I finally received an email from Flora Mohale asking for my ID to sort out the ONE STATEMENT I have asked for, Im not asking for anything more! 6 days later I receive an email that it will be done in 7 working days, so I assume, since she asked for my info on the 10th, that I would have this by the 18th February. No, I follow up on the 19th, no response, I follow up today, 23rd, no response. How can it be so difficult? Why do I have to resort to laying a complaint on Hello Peter, before I get any form of a response? All I asked was for a statement so that I can see how much more I owe, and how often you guys billed me for the smses I DID NOT ASK FOR.
