biggest mistake ever made

i app**** for a coricraft card, gave all the details and got approved and bought the couch. i didn't notice the first debit order going off. so i went into the store to query they told me my account was blocked, only to find out that they tried to call me on a number i havens used in 7 years. (remember i gave them all my details) during this conversation with the call centre they told me my account it paid, this was confirmed by two consultants. On the 14th of Jan i got an sms about an outstanding amount, i called on the 15th and spoke to a gentlemen, he assisted and told he is going to sort out my bad credit and would call me the next day to advise the outcome and to confirm they EFT payment i made on the call with the consultant, today i called to follow up and they the very rude and unwilling to assist consultant advised me they dont have record that i even called in on the 15th, this makes me concerned as they say the calls are recorded. The calls centre agent is very unwilling to assist, they either drop the phone in my ear or give attitude. when asked to speak to a supervisor they either in a meeting or already left for the day. On the 15th i was on the phone for 19min today i was in total on the phone with them for 1hr. needless to say the matter still hasn't been sorted!!!!!!!!!!!!!! COME FETCH YOUR COUCH BECAUSE ITS NOT WORTH THIS DRAMA!!!!!!!!!!!!! WORST WORST EXPERIENCE . LUCKILY I RECORDED ALL CONVERSATION AND IAM GOING TO TAKE THIS FURTHER, PEOPLE NEED TO HEAR HOW CLIENTS GET TREATED
