MAKRO ONLINE CALL CENTER SHOULD SUFFOCATE AND JUST IMPLODE!!

the worst online service ever! first time buying from Makro online and wont ever do that again, I will tell everyone not to buy from Makro online!! The kettle I bought says 2l, when it arrived the box says 3ls at the back and when you fill it , its 1.5l, it was collected on 22 March, to date no refund! email received to say it was approved and will take 7-10 working nothing called they said it failed, must send bank confirmation letter, sent that and still no refund, been spending so much money calling and waiting to hear bull****, its been escalated and no one can help except finance and they cant get hold of finance, they start at 9am! we called at 8, then they said it was refunded but nothing is showing in my bank account , called again for them to send me proof, the same line every time, it has been escalated! how can such a big business carry on this way! they is no manager or complaints team, no one calls you back , no one takes accountability to resolve a customers query, I have sent numerous emails shouting and complaining via email and nothing. Like its a black hole wherever this call centre is! The staff are all so useless, terrible, horrible pathetic,there isnt enough words to describe how bad and its all different people and they are all the same! how can I get my money back :-(, I am at my wits ends! I am exhausted from explaining the same story to everytime, complaining all the time sending emails, they dont have the mental capacity of basic human intelligence!
