Poor service

On the 5th Aug, I activated my sim card. On the same day I sent a mail to support to cancel, because there is not steady connection, at times no connection at all. I received a response that an agent will contact me within 24 to 48 hours . today is the 11th August, still no response. sent a few reminders still no response. I am sure they will deduct the funds from my account. I have see some responses to a few complaints the response is the same I quote "Trust you are well and keeping warm. Please accept my humble apologies for the service that you have received thus far. Please note one of our agents will be in contact with you to assist . Stay safe . Regards Fattima " unquote. I hope more people will read the reviews before signing up. i think option now is to contact the ombudsman..
