Spectranet — Wrong statement and cheating by spectranet

Address:

Bangalore, Karnataka

Sir,
i was promised that on payment of 6 months subscription in one go i will be given one month free of service ad same has been written on the receipt bearing serial no 16954 dated 09/08/2014 for spectranet, a scanned copy of which is attadched herewith.
Now after six months of service the connection is diconnected and when customer care was contacted they refused about any such scheme and are not even willing to have a look at the receipt.
Sir this means that to extract payment from customer these big companies can go to any extent of fraud as there is no one to catch hold of them.So being a common man i request you to look into the matter and provide justice to us as studies of our children is also being affected because of all this.Now a days internet is must for all the projects and studies.
so i request you to take action immedately.
thanx.
