Poor service

I think now it's been over 4 months trying to cancel netstar go and what really is annoying is the fact that whenever I try to cancel via the bank the come back using a different reference number on a different date cause it is now deducting on the the 15th instead of month and when you call them the agent says they'll transfer you to accounts and the call ends up just dropping cause no one seems to be interested in hearing my problem and another customer service lady promised that she'll have someone contact me but till today no one has contacted me
