My Samsung A70 phone is not making call outgoing or able to pick-up/answer some calls

My cell phone is doing the same thing Samsung a70 I was told by Comcast Samsung did an update that messed up only this phone I have a seciuss heart condition and this is getting rediculous. 😠

Yes I need something done I've been going round and round with Comcast, said they are sending me a replacement but no confirmation I'm a heart patient had to leave here by ambulance several times now I don't even have a way to call. I was on the phone with Comcast 3 hours yesterday there's no proof or nothing of the call I'm ready to cancel all my services!!!!

Yes reach out to me in so mad spending hours on the line with Comcast!

My husband's Samsung A70 started doing the same thing. I called and talked to an agent 2 nights ago and was on the phone with him for over an hour. He had me do all the troubleshooting steps he told me they had to do to confirm it wasn't working. After that he told me it was a known issue that would be covered under the warranty and that it needed to be replaced with an A71. He said he made thorough notes in the call log and then tried to get me through to someone else that dealt with the warranty. He wasn't successful but would call back the next day (yesterday). That didn't happen, of course. My husband drives for a living and needs a phone ASAP. Why is this such a hard thing to get resolved??? I really don't want to go through all the steps again. IT DOESN'T WORK - REPLACE IT!

Can I get some help please??? unable to make or take calls, unable to send or receive text messages. already contacted support and did a network reset. 

Still waiting for a resolution. Text messages are now failing. Can't get ahold of customer support. Such a disappointment.

A new software update is available that resolves this issue. If you don't receive the update automatically, you can download and install the update by going to Settings/Software update/Download and install. The new Software version: A705USQU1BTH1.

Hello, the A70 phone is still supported, but not available for sale any longer. It has been replaced with the Galaxy A71. If you are having issues making or receiving calls on the A70 just download the new software update and that should resolve the problem

No But I am getting a real runaround.

This is getting rediculous!!!!!!   I was sent a samsung a51 and I can't hear calls on it very well and they said it was just a mistake so now they are going to send me the a71. Now I'm hearing they are out of the a71s WTH! You see they are not sending out new a71 they are recontioned phones ,that's not really right it wasn't our fault these phones messed up.  Comcast needs to make this right NOW we trusted you and moved to your cell service.... MAKE THIS RIGHT !!!!!

Im running out of patictes ,hours on the phone with Comcast then send me the wrong phone a51 a lower level and still charging me for the higher level a71. Said they are going to be sending me a a71 but it's not going to be a new phone reconditioned phone 😡. I didn't sign up for this Comcast you need to make this right!  No I'm not going to set on the phone anymore for hours and get told something different by each comcast rep.
