Idea Cellular — Worst network and no cooperation from customer service

Address:

421201

I ms. Stuti sharma is complaining the kind of service the idea cellular is providing. The worst network the idea provides after launching the 4g. Neither 3g or 2g is been connected from last one week.
And i have called the customer care 15 times just they inform to do the changes in mobile settings. On 10th june i visited idea gallery near dombivali (E) they just did some changes in mobile settings that's it. Still no network is been there in the mobile.
On 12th june when i registered a complaint they stated that the issue will solve on 16th june.
What kind of service this company providing to solve such a small issue they take 4days. If this the case idea will not be able to provide good service longer any more in a city like bombay.
