complaint but no assistance

I had a complaint with regards to the collections department and nobody contaced me, I still have the same issue I raised on hello peter but the person was very quick to respond on hello peter saying they contacted me, left no contact details or a name but rather the call centre number. LACK OF PERSONALIZED SERVICE. I have an email address and a cellphone number so if you fail to reach me by call all other suppliers reach out by email to ensure that the person complaining reaches the person dealing with this directly. so can somebody who actually cares contact me.
