Epson SA - no accountability for their defective products

Epson is responsible for using repair partners at their demise. This review is pending the outcome of my query. To provide context I booked an Epson printer in for repair whilst under warranty. It was returned to me with an amazing list of new parts during the festive period however it failed to work and the exact issues persisted from before. Ethical or non ethical business practise - were the parts actually changed? Printer has been with Partserv since January and now the fault is mine as it now falls out of warranty period. Partserv went on further to confirm delays were created by Epson delay in approval. Epson denies any doing and goes onto confirm that issue lies with partner's - "Partserv" . Makro is in the dark and so am I?? I placed two calls to Partserv today requesting to speak to an authoritive figure but to no avail. Humbly awaiting a response. I just need the printer repaired as it was supposed to be, I think that's fair. JND44644
