Horrible Service DONT OPEN ACCOUNT WITH THEM

I would like to lay a complaint against Hifi Corp finance department. I made payment on the 8th of January even sent proof of psyment to them and recieved an sms after sometime saying my issue was resolved but today I get a statement that does not show the amount I paid and my account is still open when I asked for it to be closed. I had to call numerous times before getting an sms I kept being given different numbers to call and I never got through the finance department
