Shocking incompetance at MWEB!!!

I am absolutely shocked at the incompetence of mweb and their Abuse centre. We have contacted them on numerous occasions to enquire why there are spikes in our data usage which we know nothing about! Their feedback is that they cannot tell me!!! I am paying for a service and they cannot tell me what i am paying for and why there is a problem. They said they would monitor the account - that is their solution! We have had another spike and still no feedback from them. We now have no data and dont know why - neither does Mweb. Oure usage is minimal average 50-120mb per day.<br> <br> As an ISP i wouldnt touch them if their systems, knowledge and customer service are so lacking!!!!
