Worst service from **** company called Standard Appliance Repairs

This is the worst service provider that one can ever give business to. The charged we R850 on email to come fix my washing machine but when they got to my house the price suddenly moved up to R1400, unsuspecting me, i paid them, they changed the pump and on my first wash the same issue reoccurred, i called them same day and they promised to come back the following Monday, it's been 4 weeks now waiting for them. They don't want to process my refund and the owner by the name of Stanely Khumalo is ignoring both my calls and emails. DO NOT USE THESE GUYS, THEY ARE A ****
