Plumblink has no customer service! Disgusting

I had a business account with plumblink, sold my business to my ex husband and in process he refused to give me a copy of deed of sale. ( messy divorce) I did my part and informed plumblink head office telephonically that they need to contact him because the CC docs have changed and there is a deed of sale stating that he will re-apply for all accounts and he takes over the debt of the business. I then proceeded to put and confirm my telephone conversation in writing on email with all relevant info as to get in touch with him so the account could be transferred. I even receive a response from plumblink headoffice saying they will do so. Ta-Da... they never did - instead he bought stock and never paid and they lay a default against my name on the ict. Nice. I got in touch with Plumblink locally and the poor manager tried his utmost to help me get in touch with Lizelle at plumblink headoffice x3 times he’s said she said she would call me to hear what happened, she never did. No one called me again. Instead today.... I receive an email that was dated in June 2019 - them asking for my document proof the business was sold. ***!!!!! If I was called and if the original email I SENT informing them that the business is no longer on my name was read by Lizelle or Rashid or whoever is the big boss, they wouldn’t even put that on an email asking me again. MY EX WAS A ****** AND HAS THE DOCUMENTS BUT NEVER GAVE ME A COPY, instead he kept it as leverage through our divorce. Plumblink was always quick to call when there was a delayed payment, but when I ask and give them the details to call the new owner they don’t do it. INSTEAD,MY NAME GETS DEFAULTED AND MY CREDIT RECORD GETS HURT.

Thanks PLUMBLIN****!
