NO FEEDBACK FROM SALES TEAM ON NEW DECODER UPGRADE!!!

Been calling for the past 3 month to get a new decoder, every time the call centre ensures that they will inform sales team to contact me. Still no response... cannot get hold of them directly and the current Explora 2A is no longer working for the past 3 months - been paying every month for no service. Horrible customer service as there is no follow-up and on communication is either not getting through or being ignored.
