Bad service

I sm highly dissapointed again for 2 nd time with the cancellation department, i have send an email requesting tracker to be cancelled for my dad which i recruited him to join when i joined an now you guys are not responding to the email. Email with request was send yesterday an his contacts was also placed on email as he is a pensioner an doesnt have access to emails an i was not responded. We would like immediate cancellation sue to poor service which also caused me to cancel last teat an he is slso facing same issues
