I've had just the opposite experience, but that was quite a while ago. Back in the old days of VCRs I bought a plan mainly because it included free cleaning. I dropped off a VCR and nearly a week later it hadn't been touched yet. So I brought in my service contract which had the cancellation terms on it and told the manager I wanted my VCR back immediately, was cancelling the contract and wanted a pro rated refund as specified. I have never seen people there move so fast because the manager did not want a cancellation on his record. The VCR was cleaned in fifteen minutes and he gave me a gift card for the full amount of the contract (not pro rated) and let me keep the contract. I never got another service contract there again.
If you are basing your experience on VCR cleaning might I suggest coming into the 2000’s :-)
My experience was with a $2500 TV that they replaced in full. Zero questions asked. Times have changed a bit :-)
