Bad service, no feedback.

I am still waiting for my data verification since Beginning September as to why 6Gb of data disappeared in a matter of 2hours while I was not using my wifi. They said I would receive the data verification in 3 days time. When I phoned back after 2weeks they said they were waiting for month end to send it to me but no one even phoned to let me know. Month end came and went, we are now in November and I still have not received it. I made how many calls and each time I get Promised they will send it. It is really disappointing since I have 2 contracts with them but they can quicly phone me regularly to ask if I dont want annother contract, very disgusted by this bad service.
