BAD POOR SERVICE

I opened an account with JDG which works hand in hand with Hi-fi corporation in 2016 December, I then paid the account in full November 2017 and I even received a confirmation letter to prove that the account was paid and closed... 3 months down the line I start getting abusive call from different number, everytime I called I was told am owing, I explained my self from the 1st of February and even sent the letter to the email address I received from JDG, I then called in this morning to complain and I spoke to a gentleman who said he was the manager, he assured me that everything was being sorted and told me that I was going to be debited for something that am not owing

MY QUESTION IS WHY DID YOU WAIT FOR SUCH MONTHS TO TELL ME THAT AM OWING, YOU CLAIM THAT YOUR CALL ARE RECORDED SO WHY DIDNT YOU GO BACK TO ALL THE CALLS I DID FROM LAST YEAR WANTING TO CANCELS THAT CONTRACT,

EVERY MORNING I NOW WOKE UP WITH A CALL FROM JDG ********** 609 ********** 486 ********** 124 ********** 040 ********** 028 ********** 338 DAY IN DAY OUT

AND THIS IS THE SECOND TIME AM BEING TREATED LIKE **** BY YOU GUYS

NOW YOU HAVE GONE AND DEBITED MY ACCOUNT WITH THOUGHT MY PERMISION.....AM REALLY ****ED OFF AND I WANT SOMEONE TO CALL ME TODAY AND THIS TIME YOU WILL GIVE ME SOMETHING FOR FREE FOR THE INCOINVINIENCE ON THIS NUMBER ********** 102
