Standard bank service

I reported a cash withdrawal problem on 29 April 2015 and I was given a service request number and informed that it will be resolved on 07 May 2015. However, on 07 May 2015 I received an SMS informing me that the matter is still in progress. I followed up on the matter on 25 May 2015 and I was informed that it is being escalated to the relevant department. I followed up again on 08 June 2015 and I was informed that they are having technical difficulties retrieving the details of my request, but it will be escalated to the relevant department. I followed up again on 17 June 2015 and I was given a new service request number because the matter has been hanging for a long time and it will be resolved on 24 June 2015.On 24 June 2015, I received an SMS informing me that the matter is still in progress. Followed up again on 02 July 2015, I was informed that the matter will be escalated to the ATM division. it's over two months and I'm still not getting any feedback on the matter.
