Blocked card with no authorisation from me

I called your call center enquiring about a purchase that took place on my account, the agent advised me of blocking my card and I specifically told hee I do not want to block my card and she cut my call. I realized later that day when I tried withdrawing money from atm that my card has been stopped. The entire festive period I have no card to use as I am waiting for the compliant I logged. I want my card unblocked or you issue me another card and it must be delivered to me as I do not have the time to go to the bank. I am so annoyed with your service lately, it is pathetic
