Woolworths Financial Services SPAM call nuisance

Years ago I was inundated with calls from woolworths financial services - untill I finnaly conceided and agreed to obtaining a credit card - on condition they will stop calling me. The calls have not stopped - I still get bombarded with all types of sales - and the calls are accompanied by SPAM calls from ABSA also trying to push products. I have recently experienced problems with my credit card - only to find out that it was blocked - I DID NOT ASK THEM TO BLOCK IT - and was told that they tried to call me - but when I didn't answer they decided to block my card - I have now spend countless calls on phone and even drove to woolworhts to sort this out - but everytime calls have to be logged to Woolworths Financial services and then to ABSA Credit Card department - and on 3 x occasions the calls got dropped (probably because your lines are occupied with telemarketers irritating clients like myself)
