WWICS Group — breach of data and plenty of errors

I would like to warn everyone before approaching wwics. I made a huge mistake by trusting them. They made so many errors at every stage of application, did not meet the promised timeline, very unprofessional, their attitude is totally different after you pay the fees. You just don’t exist for them anymore. Worst was they send my whole pnp file to some stranger with all my personal details. I must have called them 100 times and messaged officially for withdrawal of our case and refund our money as i don’t trust them with my personal information any more. They don’t pick up my phone and if they do, they find some excuse and cut the phone. Last 3 months have been the most stressful because of them. Some one please help me
