Tata Docomo — bill amount very big to uses

Address:

Ahmedabad, Gujarat

I am using TATA DOCOMO postpaid number. i put request on post paid to prepaid change. Till now it didn't get changed .i cleared my current and unbilled amount when i raised requested that time till now it is not getting changed but bill generating TATA DOCOMO cheating me.i am calling daily and spoke to customer care they are telling it will change tomorrow or else they are telling technical problem i did'nt understand is there any technical problem in more than 18 days. This is the worst customer service i am facing in my life time. I checked with docomo store also they are also telling server problem.if you are not resolve customer query certain time what is the use of having customer care and store.i am very much irritated this customer support.i am keep sending mail to customer care they did'nt respond at all.i lost my hope there after it will change or not. my tata docomo number : [protected] Name:Mehul Vaghela
