"UN"RELIABLE store worst online service

Firstly, this online store claims to have the best nationwide delivery and promise delivery within 7 days when you place an order. I placed an order on the 17th of July this year. On the 26th of July I requested an update on delivery at which time I was informed that they only receive tracking numbers 7-14 days after purchase was made. I eventually received the Item on the 26th of August but it was not the correct item. I immediately notified them and was asked to send photos of the item I received and what was wrong with it, which I did. On the 1st of October I requested a refund as they never got back to me. I was asked to be patient and that they were still waiting for a tracking number of the replacement item. On the 10th of November I wrote another e-mail but it was ignored and I'm being ignored until now. I feel that they are ***** and are very "UN"Reliable
