Bad service..

I opened an account with Homechoice around May and placed order by 29th May 2020. They keep billing me for something that they have not yet delivered...i called to complain but no-one helped me..i then emailed their delivery services they shifted blame to their courier company. I emailed both customer care and delivery since they promised to get back to me and they never did...their lines are always engaged and whenever they answer the staff is rude...up until today 2 months later i have not received the order but i have been billed twice which on their website it states that they don't bill customers before receiving items.. Bad service from every department i have contacted...one cannot even reach their courier company.
