GLOCELL *******

Glocell has been deducting money from my bank account for the last 10 years. I spoke to so many consultants over the telephone over the years and every time when i ask to cancel my contract, they say they did but still like clock work, at the end of every month, Glocell debits from my bank account. I had a contract with them in 2008 and after that 24 months, they contacted me for upgrade, i said i don't want upgrage and contract with Glocell anymore, but it's been going on ever since. Can somebody please help me stop these people taking my money ???
