Mr Price Stores

I'm so disgusted in Mr Price seriously we have a account with them we pay them every month on time bt the credit disappears, eventually we went to the store to cancel whatever stuff it is on the account that they said is taking the credit after doing this at numerous stores we decided not to pay one month an wait for head office to contact us which obviously they did the very next day after payment was due.Even they said there is nothing they can do about the credit that disappears we must go to the store an they of no freaking help.so we decided we not going to buy anything an just pay we did that for 3 months now an then boom guess what we have no credit I mean like seriously I'm disgusted an no one in the store or head office seems to care or even take note of our enquiry.this is the worst store ever to have a account.
