Hi,
My cug plan changed without prior intimation and internet capping limit being levised on the same number, due to which the bill has increased immensly and even after speaking to customer care there has been response like that company can change postpaid plan and it was changed without prior intimation. My postpaid bill is increased tremendously.
This is really service, affecting the brand name by poor work.
