Lack of response and accountability between Epson and Partserve

There inherent lack of proactive support. Unfortunately partserve channel support seem to be the only supplier assigned to service Epson products in the whole of Cape Town. I have been having an issue with my Epson L3150 ink tank printer (Serial Number : X5EG012259), for weeks on end. I have two separate jobs linked to the same issue; JNC37954 & JNC38454. What has not been taking into account or considered by partserve, is the amount of follow-ups, (emails, phone calls, trips in the car to take my printer in) etc. The @Epson promotion and warranty is not worth the money and effort when this is the level of aftersales service. I have been without a printer for +/- 5 weeks". Despite the Cape Town Branch manager been accommodating, I don't think the full extent of the impact to me as a customer has been considered or understood. Because despite changing parts and saying there is nothing wrong and making me feel like I was lying, finally they Sen the following message "The Epson adjustment tool gives a unknown error 034004 fatal error and a 100016 scanner fatal error". Despite this been sent to Partserves headoffice and despite my machine being under warranty, I have not received a response in a week. despite 3 requests for feedback. This is the problem when services are outsourced! as the end customer in this scenario, please tell me who is accountable to meet my needs. I am stuck between Epson and Partserve and neither organisation's seem to care or display the expected level of ownership to resolve my issue! Such a poor Customer experience to date, would never wish or recommend that any customer have to endure this in any shape or form!!!
