Discovery card - Poor service, poor account management negatively affecting my credit rating

<p>I called discovery card to close my account beginning July, because I was not using it but kept paying the monthly fee to keep a good status. Was emailed forms, completed and sent back. 2 weeks later, with no correspondence from discovery card called in and was told there's a credit owing to me for a health wallet benefit not used this year. Only to find that my internet bank reflects that I owe them. A week later I call & told it's a mistake as they owe me. A week later still unresolved I call again, now I'm told I owe them and raise a compliant. During this time FNB is calling me everyday to make payment. Still no correspondence from discovery, I call again and told a new compliant is logged. I subsequently get an email from Romeo Luthuli that I need to pay them which I respond to and call again. No feedback from anyone at discovery. My account is still reflecting negatively impacting my credit rating as I'm in the process to buy a new house and it's now another 2 weeks without resolution or a call. This is very poor service from discovery card, considering I've been a loyal customer for over 11yrs. No one there knows what is going on and management doesn't take any accountability.</p>
