I have experienced the worst customer service from Mark Electricals.bought a cooker from them and purchased a 5 year parts and labour with it. Rang them to supply the spare cooker part.rang every week for 8 weeks even spoke to Charlotte to resolve this.Even e-mailed them without a response.they never phone you back when the manager says they will.The only way to send your complaint higher is by sending an e-mail directly to the customer service themselves which they never respond.You cannot even escalate this further to the head office as it's the same address. Rang every week and was told they are looking into this.after chasing them for 8 weeks was told that I had to pay for the parts even though I paid for the 5 years parts and labour.Really disappointed in the service,will never buy from them again.
