Tony & Jackey promo from Metrodeal is a scam

I'd like to share with you our experience with Metrodeal and Bang's Tony and Jackey, Tomas Morato branch. 
Before anything else, we are loyal customers of Metrodeal and we've purchased and enjoyed several deals from them. I was a bit reluctant to buy the rebonding promo since I have very long hair and might end up paying more to get the hair treatment. I also noticed that the fine print showed "Tony and jackey reserves the right to deny service in regard to hair quality of customer" - twice, but i still did which I eventually regret doing. Anyway, my boyfriend and I went there this morning since it's the first day the voucher can be used. I approached the front desk to show a copy of the voucher and the first thing that came out the receptionist's mouth was, "Ma'am di po kasama ang treatment saka cash lang." Wait lang ate, wala pa ko sinasabi ha. sheesh. So I just smiled and asked how do we go about this. She went on trying to upsell, "ma'am kaylangan po i-treatment ang hair mo pero pa-check muna natin kay stylist." She had me sit on a chair and asked  the Korean guy to inspect my hair. After a few seconds, the korean guy said, "need treament." At this point, I was already having a hard time maintaining my composure because I had the feeling these people is starting to tell me that they don't want to do this. With all my strength, I asked how much the treatment would be, "3 thousand po ma'am". WOW ha. So ano pala ang na-save ko sa deal na yan? According to the deal, "Hair Blessing Rebond or Digital/Setting Perm & Haircut at Tony & Jackey for P2999 instead of P8500", the 8500php was for the rebonding alone. Seriously? I know it's a bit more expensive than your usual salon but 11,500 pesos for rebond and treatment? wow. We left the salon and started calling Metrodeal hotline to get a full refund. The person I spoke with clearly had no clue how furious I am since she kept on saying she can't give me a refund now. I escalated it to a Manager and spoke with Donald whom started to say the same thing. Eventually, he made a report and promised me he'll give me a refund through Metrodeal credits since crediting it back to my account would take weeks. I will post another blog once I get a response from their team.
