Airtel — [protected] - airtel employee abhishek sharma forced me to request him

Address:

711303

Dear sir,
At around 7 am today, airtel employee abhishek sharma bearing no.+[protected] contacted me after i lodged complain on 4g speed at every night here, forcing me to request him. And i did not know what grounds i have to request him. This guy disturbed my sleep and he spoked in hindi in almost inaudible voice. His language is also not recognised. He ended like stuttering.
In the end my 4g speed problem remains same.
Plse provide further guide into this matter
