401 Auto RV Canada

After we purchased our trailer and it was delivered to us, we quickly realized that there were issues with the water tank. It overflowed and there was an accumulation of water in the underbelly of the trailer. We spoke with *** who told us to perforate the underbelly and to let the water evacuate and that she will send a technician to change the underbelly and make the repairs.
The technician came, did not do any repairs, resealed the underbelly and left. We contacted the *** of Campmart and he sent the tech back to do the repairs while I was present.The technician made a modification and once again resealed the belly and left.
I contacted *** to inform her that the tech left the brake wires uncovered and did not change the underbelly. She informed me that they will need to bring in the trailer to change the underbelly.
A week later, I emailed them again to follow up as I did not hear back from them.The warranty department contacted me to let me know that it was not covered. I informed *** from the warranty department that I had an email from the , ***, stating that they will honor it and will proceed with the repair.
The last communication was on August 28th and they blamed the delay on Covid and that they are waiting for the part. The initial issue arose on August 8th and they were informed on that day. I emailed them this morning, but did not receive a reply whatsoever.
