Appalled

I purchase my car at the General motors in the west rand (CMH group) July 2013 everything went well, I was sold a dream ... signed, sealed and delivered, <br> I never had a problem with them I have been a happy customer thus far... however last week ( 3rd and 4th) when I called in to enquire about my extended warranty that when the disappointment kicked in... no one could assist me as is I am still waiting for a call and by the looks of it I don't think I am going to get that call...<br> I initially called the number on my contract, it didn't go through, then I decided to call another branch (East rand branch) they told me that the west rand branch has closed down and they can`t help me I should contact the bank that I am financed through..<br> I then proceeded to call the bank they explained to me that my warranty was done through the dealership they should help me out, I then proceeded to call the East rand branch as they were my best option seeing that the West rand branch is no longer in business but then I was told right there and then that they don't have my details on their system, which was shocking absolutely shocking, one company - I get it's a different branch but fact
