HARRASSED BY VIRGIN ACTIVE HEAD OFFICE

I DOWNGRADED MY MEMBERSHIP. THEY GAVE ME THE OPTION TO PAY THE 'ADMIN FEE' AT THE GYM. NOW THEY PHONE ME 6/7/8/9 CALLS A DAY TO TELL ME MY ACCOUNT IS IN ARREARS. I HAVE EXPLAINED COUNTLESS TIMES I WILL PAY WHEN I NEXT VISIT THE GYM, LIKE THEY GAVE ME THE OPTION TO. I HAVE EMAILED THEM DIRECTLY TO COMPLAIN ABOUT THE HARRASSMENT BUT THEY KEEP PHONING ME.
