Pirelli Tires review: Rebate

Applied for Pirelli's 2020 August September $70 rebate, sent the required form and receipt in on 9/14/2020. Attempted to call the number on the form to find status numerous times, only got an answering machine, left name, address, phone number, email never got a response. Sent emails to address on form requesting status of rebate and just finally got a response. It told me they are busy and to wait another 6 to 8 weeks. Unsatisfactory answer. Read on web that other peple don't get the rebate and feel like I'm going to have trouble getting mine. Thank you.
