Sick of complaining now!

Since the past one week I m trying to renew my net account, but somehow its not happening. When u book a renewal pack , how happily these call centre ppl tell u,"Mam, ur pack will reach u in 48 hrs." Forget 48 hrs, it reached me after 144 hrs... Now thats a bit too much! Wait wait the misery does not end here. When u try to renew ur account, the pin no is faulty...Phbbt! Seriously I have lost the patience now. Trying my level best. I dunno when i will b able to login now. Tired of complaining again again!!! Grrrrrrrrr!
