Prior to initiating descent to ZZZZ1; the flight crew contacted ZZZZ Center and advised that we were unable to accept RNP-1 (Required Navigation Performance) arrival procedures. At this point; Center instructed the flight crew to fly an RNP-1 arrival despite having been informed of the incapability and the flight crew reiterated the fact they were unable to accept the arrival. Instead; the flight crew requested to fly direct to ZZZZZ waypoint for the start of the RNP RWY (Runway) XX approach. However; Center ignored this request and instructed the flight crew to fly direct to ZZZZ1 VOR and expect the VOR-A approach (Jeppesen Plate [Page]). When the crew once again requested to fly direct to ZZZZZ for the RNP RWY XX; Center repeated the instruction to fly direct to ZZZZ1 and expect the VOR-A approach without further acknowledgement or explanation of denial. The flight crew speculated that Center's refusal to assign the RNP approach was due to misinterpretation of the flight crew's inability to accept the RNP arrival; and efforts to clarify this case were also ignored by Center. The Captain (Pilot Monitoring) selected the VOR-A approach in the MCDU (Multi-Purpose Control Display Unit) and verified the route information while the First Officer (Pilot Flying) briefed the approach plate. At this time; both crew members observed what appeared to be inconsistencies between the MCDU approach database and the Jeppesen approach chart; specifically that the waypoint on Chart X did not match the waypoint shown in the MCDU routing; nor did the MCDU approach procedure indicate the required procedure turn under routing [FLP page] or Procedure Turn Info page [NAV - Page 2 - Patterns - Procedure Turn]. As the workload for the flight crew increased due to the inconsistency between chart and MCDU database; Center's refusal to assign a more effective approach; continuing descent towards mountainous terrain; and multiple segmented and non-standard clearances from Center that threatened to interrupt critical flight deck operations (notably the approach briefing); the flight crew elected to fly the VOR-A approach under raw data (green needles). All elements of the planned approach thus far mentioned became void after the flight crew received the hand-off to Approach Control who instructed them to fly direct to the airfield and complete a visual left-hand traffic pattern from overhead the runway.This flight crew highly recommends that an investigation be conducted into inconsistencies observed between the Jeppesen approach plate for the ZZZZ1 VOR-A Approach [Chart] and the MCDU database for the EJET fleet; namely the incorrectly labeled waypoint identified as ZZZZZ1 on the chart. This flight crew also highly recommends that effective communications be made between [Company] Flight Operations and the [Country] Air Traffic Control agency to ensure better understanding of which procedures [Company] flights are able to conduct and which procedures they are not; specifically the differences between RNP-1 'Arrivals' and RNP Approaches.
