56 Days later, No resolution and no feedback

After 48 days l wrote a complaint on this forum. My issue was escalated to headoffice from reference JO-LG-*** to *** and l was promised the area manager will contact me in 3 - 5 working days. After 5 working days, the AREA MANAGER has not bothered to contact me, and again reflecting badly on a already frustrated customer. Can this issue be escalated again to the regional/Operation manager or the CEO. In short, my issue is that l returned a faulty TV to JD/Russell Kempton Park. After 30 days, I was given a replacement tv which was not the one l had purchased. No one bothered to inform or get my permission concerning the new tv. To make matters worse, when returned my tv l explicitly stated to customer resolution centre and the store manager that l did NOT want the new model replacement as it did not have the function ability that l wanted (its actually an inferior according the specs on LG tv). I just want the tv l bought from the store.
