Pathetic Service from Absa Call Centre

i'm very disappointed with the service level of such a reputable company as ABSA. i'm disgusted that the call centre agents will continuously call you to make a sale yet when you want a Manager to call you no one will reply to my call because it is a complaint. I cannot understand how the Management Team in Absa works. Firstly I had a call from the Absa Call Centre that was pitching a Credit Life policy to be added on my credit Card. I told him 3 times that I Do Not want it and he still went ahead to add it on my account. Secondly I go to the Gateway Branch to lay a compliant they direct me to the call centre again were I phoned from the Branch the agent advised to go to the counter and fill in a cancellation form. For what I asked because I will not cancel something that I did not approve off in the first place. she advised she will get a Manager to call me. this is more than 2 month ago and no one has contacted me. it is highly frustrating now because of the incompetence of that ********** agent from ABSA Call centre has caused me my time and money being debited every month when clearly I stated I DO NOT WANT IT. before they speak to you they say all calls are recorded. they need to go listen to the call and sort out my issue. So I hope now that the Management Team will wake up and do their Job properly. this is really pathetic and disguising coming from ABSA. so much for valuing your customers. 3 occasions I still get a call from the ABSA Call Centre and laid complaints with them and they said no problem my Manager will call you, last call was on 12 July 2018. Im still waiting for that call The agents call me all the time and when asked to get a Manager to call me they say yes and no one does. I do not have the time to check my statement every month and I have trusted that Absa will not do this on my account - This is regarded as *****.
