Close account and *** service

Ive been paying my account each and every month, but still being tormented even at 9 at night for payment being phoned and treated like a ********. Ive made arrangement with every consultant that phoned every single day but no one have the arrangement on their system! ***! Now that ive settled my account NO ONE can assist me to close this ****ty account. Im sick of the disgusting service and consultants screaming at me over the phone and treating me like this. I swear if one more consultant tells me to phone again the next day i'll loose it! You have no respect for customers, and no right to talk or treat us as poorly as you do. I wish you'll close your shops and do everyone a favour!
