mobuis bad service

I contacted mobuis for a data contract and they offered me a 1500mb data package. All was well. And I took the package. In the first week of receving it I have used 500mb. And then they ut it off. And told me that it was that package. So I called them and canceled it. And had to send emails. I did that. It is now I think about 2 years now and they are still phoning sms email me to get me to pay. I told them that I wil not pay ever for these poor tipe of service. I wil not pay for service I dont received. It was canceled in the first month as they said I can do if i am not happy. I am verry verry dissipointed in there bad verry bad service please. I had to put 1 star rating to whrite this but they dont desirve it thanks.
