Grandshoes worse experience......ever my first time and last time purchasing your products😪

Worse experience ever with Pinestreet shop Gand shoes they don't value their customers, i bought a shoe which was for relieving me from the heels after funeral, guess what few hours later the pams were torn, hell no......not the expensive ones like that. I took it back and explained to them and I was willing to take anything of that amount because real fixing them is not a guarantee that I will not experience same fault next time I wear them. till this day my issue is not resolved I have been looking for regional manager without success I keep on leaving my number they not call me back even though they know my problem I am told she still to investigate. I was willing to take the product that is equivalent to the price I used since they said they dnt do exchange sales product. now I am no longer patient amd will to hear any of their products I need my money. this is July case amd we in semptember now and I do not know what is going on .what anoid me most Iphysicaly went they 5times already trying to resolve the issue but without success. What I need is my money back I am no longer interested on their terms and conditions.
