poor service disrespect and unprofessional

there's a hugh problem with mbd customers service department and I'm unsure as to why creditors are allowing them to handle their accounts as they are furnishing the creditors names, yesterday i was put on hold for 2 hours for requesting a prescription letter for the account i had with standard bank as standard bank bank kindly asked me to contact them because the account was ceded to them in 2019 I've tried making contact with them several times but as soon as they hear its me they laugh and hung up this things should be taken serious we not using sweets to call them and experience their playful consultants their email is worse where is the counsel for debt collectors they should really intervene in such disrespect
