No Response At Nedbank

We were **********ly put under debt relief in January and the Debt Relief Company reversed this on 31st January. Since then, all our other facilities have been restored except our Nedbank credit card. Frustratingly we deposited R40,000 last week. Our facility is till flagged. Yesterday we phoned and were told to email proof at *** za which we did. No response. Not even an automated response. Why? Are we using the incorrect email address or is this your new style?
