Bad customer service

I bought my phone at foscini on the 25/07/2017 and on the 09/08/2017 I returned it to the shop as it wasn't charging.

I was told that it takes a month which I wasn't happy at all as I'm self employed and I relly on my phone for business purpose I had to sacrifice but today I got a call from the shop informing me that parts has been ordered and my phone its still no ready and it will take 7-14 days to repair depending on the problem of the phone otherwise it might take 21days.meaning it now be 2 months without a phone

For me that is unacceptable and unprofessional,how am I suppose to run a business without a phone?I bought the phone mainly for business and now I'm really struggling which is absolutely not my fault.I suggest that I get a new phone or you guys give me borrowed phone to use until the mess has been sorted out..

I really don't understand why I have to stay 2 month's without phone,kindly escalate my complaint and cc me on your email as I'm really not happy.looking forward to getting the respond ASAP
