Worst service providers!!!!!

I opted to do my notarization through this law firm. And how I regret. I was quoted R4200 and they only did half of the work. This also included the application for a Police Clearance Certificate. Two months passed and no progress. Eventually I asked my friend to follow up at CRC and my certificate has been there. I had to pay again for a reissue. So I asked them to stop everything since there was no progress anyway and requested for a partial refund. Till this day they're still "reviewing" my file. No communication (another reason why I requested termination of services). They're literally not replying on emails. Worst service providers ever!!
