Bad service

I tried to apply for credit card, got declined. Was told I need to upgrade my account from pay as you transact to discovery gold bundle account for me to qualify which I did. But was still declined even after changing the account. I app**** to two different banks and was approved for higher amount on both banks but Discovery keep on declining, however that is not the reason I'm writing this complain. After they declined me, I requested that my account should be downgraded back to pay as you transact in August, They sent me an email to confirm that it was changed. To my surprise month end September was charged fees for gold bundle account, When I spoke to the sales consultant was requested to send an email again. The following day I got an email confirming that it was downgraded. Today I decided to call to confirm the changes since I didn't want more surprises this month end, and was told changes were not done, the only change that was ever done in my account was in July and unfortunately this can only be done in 11 days and be effective as from month end November. Meaning I will have to pay fee for Gold bundle account again this month. To me this look like they just wanted to get more money from me for monthly services charges. I need this to be resolved as soon as possible.
