Worst service ever

I purchased a laptop on account at Hi Online and as per stupid procedure my account was blocked a few minutes later. I then received a call from them for me to confirm that i did the purchase. I then confirmed and was asked security questions.

But when i try to purchase on my account it says that this card is currently blocked.

I then called their finance department and was asked more security questions and was told the account is unblocked and that i can try again. I tried while she was on the line and still nothing.

Then she placed me on hold and came back and asked me again if i could try again. I tried and the account is still blocked.

I am sick of the service or lack thereof that i receive from this company. You guys increase my credit every month but then **** with me when i need to use the account.

And please advise why you have to block the account everytime a purchase is done???

Please correct this i am sick of the poor servive.
