Hathway — Receiving nuisance calls and messages everyday

I used Hathway in past and because of poor services from Hathway I switches to other service provider. There are no dues or anything which is pending on my account as I was using a prepaid account and I also closed my account properly through the proper channel as per Hathway procedure.

Now I am continuously every day receiving calls from Hathway and the tele callers are saying that they will not stop till the time I will not renew my account. They have been very rude to me and keep on calling me everyday. I do not wish to receive any calls like this from Hathway and people talking to me like this in this tone like I owe anything to them. Please make this stop or I will have to file a formal complaint against Hathway of harassing me and pressuring me to do something which I do not want to do.

My old account number with Hathway was : [protected]
