Unhappy customer

Am very disappointed in Ackermans I feel like am being ****med, last year had an account, struggle to pay bt eventually I payed the account in full, no money owed and I went back to the store late last year to find out if can I stil continue paying the account jst for me to have credit for when I decide to need something,I continued paying the account nd nothing was said to me about the account being blocked am only informed today now tht I went instore to do a new card coz had lost the previous card that I was blocked last year.. Now my problem is that, why can't the stores tell u when a person is block coz now these guys are sitting with my R1000 nd on top of tht am being told tht they will decide if they will do a refund or give it to the lawyers on top of paying all tht I was owing to Ackermans..
