I had the opposite occur for me. I reported a similar problem and they said they'd dispatch an engineer to check on it. Three days later everything worked perfectly.
Must be nice. For over eight months, we had no response of any kind, nor any indication that they had any interest in looking into possible technical issues on their network. In their final denial letter to us, they stated that based on the coverage map on their website, we could "expect excellent voice and data service" (at the location where we'd had constant drops for months).
