bad services

I phoned Getmore on the 29th of January 2016 to cancel its services which I don't use but pay for every month. The consultant who I spoke to said they gonna give me a call in the next 3 working days. I didn't receive the call and phoned back. They told me that my phone went straight to voicemail so they couldn't leave the message. So they asked me if they can call me the next day late afternoon so I agreed. I've been waiting and they decided to call me on friday morning rather while I was in classes. I couldn't answer. Now today when I phoned in again they tell me someone phoned me this morning. But I don't have any missed calls on my phone ????? Are you guys trying to play me? I'm going to pay again with you guys which is not acceptable because I tried to cancel a month before the time. Unhappy ! Bad services !
