No follow ups all talk and no action

This is a follow up on my previous complaint about standardbanks *********** electricians, who were supposed to repair our stove and damaged it more by wrongfully connecting wires and burned them out as a result our 4 plate stove is now a 2 plate stove. After my first complaint on hello Peter standardbank customer care consultant phoned me and appoligized and promised to resolve this matter.....well as usual it was all talk and no action and 2 weeks later and no resolution or any feed back! should we really just accept that their electricians burned out our stove and pay for their inflicted damages??? is that fair?? All reports from other electricians states the same that due to poor workmanship and wires being wrongfully connected by standardbanks electricians they caused the stove plates to be burned out! standardbank has been awarded the best bank.... my question is best bank at what??? just at talking!!
