Product reviews for CMA Inter Group 2 Managment Accounting

I HAVE PURCHASED THE LETURES FOR THE 12 MONTHS VALIDITY BUT RECEIVED ONLY FOR THE 6 MONTHS AND WHEN REQUESTED TO EXTEND THE VALIDITY. HE DIDN'T SEE THE MAIL FOR A MONTH AND WHEN AGAIN MAILED AFTER A MONTH HE SAID THAT THE VAIDITY IS EXTENDED BUT THE VALIDITY IS NOT EXTENDED. AND AGAIN MAILED / MESSAGED / CALLED HIM BUT THERE IS NO RESPONSE FROM HIM. EVEN HE DIDN'T  SEE THE MESSAGE. ALSO WHAT HE SAY THAT WE DIDN'T SEE THE MAILS / MESSAGES FREQUENTLY.  SO REQUEST TO ALL OTHERS TO DON'T PURCHASE THE LECTURES FROM HIM PAY EXTRA MONEY SOMEWHERE ELSE AS THE SERVICES ARE WORST.
