Harassment from MBD

I am also a disgruntled customer,I paid MBD last week on 6 July 2021,they call you early in the morning at 07:00 as if it makes a difference if they call you at 09:00,its harassment this people are still sleeping or getting ready for the day and here MBD calls and the calls are dropped when you answer them,I want my paid up letter and no calls or sms's that I owe them.
