Worthless deal ever!

Dentospect Dental Clinic

I took deal of Rs.129 which on mydala shows worth Rs.1500.
I have been regular for last 2 years to dental clinics though deals frm Group On.This is the first time I bought a deal frm Mydala.
The doctor tells you whatever teeth can be cleaned or polished in 10 mins that will be done ..For the leftover teeth it will be chargeable.There is nothing like that mentioned in anywhr in terms and conditions.
I have never seen received such response frm any dental deal in last 2 years.Being decent and respect of that lady who runs clinic I followed whatever instructions she told left the place.She told for rest of the teeth cleaning and polishing you may ohave to go for 3 more deals which will cost ypou around 500 in total..So you may directly approach us and get it done at once.
If I have to take such deals three times then what is the sense of choosing a deal frm MyDala.com!!!!!
If its like that it should be mentioned under terms.
Its a request to Mydala and Dentospect..Dental Clinic..If such monopoly is running frm either of your end sooner or later you may lose your credibility frm clients who ake a deal frm MyDala..
