Just got Verizon 5G after I was promised it would be a comparable service to Xfinity land line but it's not. My Xfinity landline is 10ms ping with 0 latency spikes. With Verizon Home 5G I get 50ms with packets dropped every so often with spikes going up to 300ms. If I cancelled my service now, would I lose my promo since I already redeemed them?
