Very poor customer service

Very poor customer service. Month and a half and order still not resolved. Only delivered partial of the order and been struggling for a month and a half to get a cash refund to purchase the product elsewhere or have the missing item delivered. This was a surprise gift bought for my Mother's birthday. Made the purchase on 23 July and on 26th July delivery was made but unfortunately only 1 parcel instead of 2 parcels were delivered. Eventually 2 weeks ago the distribution warehouse indicated that they will resend the order and to date never received but I keep on receiving emails to rate the service but there is no service so how must I rate it by giving it a 1 star everytime and still it won't be resolved?
